A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
Tom Lackey is an American politician serving in the California State Assembly. He is a Republican representing the 36th district, encompassing parts of Antelope Valley and Santa Clarita Valley. Prior to being elected to the state assembly, he served as a Palmdale city councilmember. Tom Lackey grew up in the small town of California, he became an Eagle Scout during high school in addition to being active in student government. He received a Bachelor's degree in Special Education from Utah State University. Lackey joined the California Highway Patrol and served for 28 years. During this time he served on the Palmdale Elementary School Board, was elected to two terms on the Palmdale City Council. While serving on the Palmdale City Council, Lackey was made a city appointee to the California Contract Cities Association, the Antelope Valley Crime Task Force, Antelope Valley Transit Authority Board, the Antelope Valley Human Relations Task Force. In 2014 Lackey announced he planned to run for 36th California State Assembly District against the incumbent Steve Fox, considered one of the most vulnerable democrats in the legislature.
The race was one of the costliest of the 2014 elections with both campaigns and independent expenditures spending a combined $2.2 million. Lackey went on to defeat Fox with 60% of the vote to Fox's 40%, he was sworn into office on December 5, 2014. Lackey began his term by declining a pay increase, approved for Legislators' salaries, he was one of six Assemblymembers to decline the raise. He is a member of the following Assembly committees: Budget, Public Safety, the Joint Legislative Committee on Emergency Management. Additionally, he is the Vice Chair of the Administrative Review committee. Lackey authored a roadside "drug breathalyzer" bill, Assembly Bill 1356, rejected by state legislators "But that bill failed this spring, in large part because THC levels are not good indicators of intoxication..." Lackey co-authored the bi-partisan and historic Medical Marijuana Safety and Regulation Act in 2015. Part of a package of laws intended to create a statewide framework for regulating medical marijuana.
Part of the law is aimed at addressing the proliferation of drugged driving in California and is funding a study at UC San Diego to create tools to recognize marijuana-impairment in drivers. The private lobbying group named "California Police Chiefs Association" named Lackey their 2015 Legislator of the Year for his promotion of on drug-impaired driving bills, he received the 2015 Legislator of Year from the secular "Easter Seals" organization for his leadership in advocating for increased funding for special needs Californians.

Death Valley is a desert valley located in Eastern California, in the northern Mojave Desert bordering the Great Basin Desert. It is one of the hottest places in the world along with deserts in the Middle East. Death Valley's Badwater Basin is the point of the lowest elevation in North America, at 282 feet below sea level; this point is 84.6 miles east-southeast of Mount Whitney, the highest point in the contiguous United States, with an elevation of 14,505 feet. On the afternoon of July 10, 1913, the United States Weather Bureau recorded a high temperature of 134 °F at Furnace Creek in Death Valley; this temperature stands as the highest ambient air temperature recorded at the surface of the Earth. Located near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve, it is located in Inyo County, California. It runs from north to south between the Amargosa Range on the east and the Panamint Range on the west.
It has an area of about 3,000 sq mi. The highest point in Death Valley itself is Telescope Peak in the Panamint Range, which has an elevation of 11,043 feet. Death Valley is an excellent example of a graben, or a downdropped block of land between two mountain ranges, it lies at the southern end of a geological trough known as Walker Lane. The valley is bisected by a right lateral strike slip fault system, represented by the Death Valley Fault and the Furnace Creek Fault; the eastern end of the left lateral Garlock Fault intersects the Death Valley Fault. Furnace Creek and the Amargosa River flow through the valley but disappear into the sands of the valley floor. Death Valley contains salt pans. According to current geological consensus, at various times during the middle of the Pleistocene era, which ended 10,000–12,000 years ago, an inland lake referred to as Lake Manly formed in Death Valley. Lake Manly was nearly 100 miles long and 600 feet deep, the end-basin in a chain of lakes that began with Mono Lake in the north and continued through multiple basins down the Owens River Valley through Searles and China Lakes and the Panamint Valley to the immediate west.
As the area turned to desert, the water evaporated, leaving the abundance of evaporitic salts such as common sodium salts and borax, which were exploited during the modern history of the region 1883 to 1907. Death Valley has a subtropical, hot desert climate, with long hot summers and short, mild winters, as well as little rainfall; as a general rule, lower altitudes tend to have higher temperatures. When the sun heats the ground, that heat is radiated upward, but the dense below-sea-level air absorbs some of this radiation and radiates some of it back towards the ground. In addition, the high valley walls trap rising hot air and recycle it back down to the valley floor, where it is heated by compression; this process is important in Death Valley, as it provides its specific climate and geography. The valley is surrounded by mountains, while its surface is flat and devoid of plants, so much of the sun's heat can reach the ground, absorbed by soil and rock; when air at ground level is heated, it begins to rise, moving up past steep, high mountain ranges, which cools sinking back down towards the valley more compressed.
This air is reheated by the sun to a higher temperature, moving up the mountain again, whereby the air moves up and down in a circular motion in cycles, similar to how a convection oven works. This heated air increases ground temperature markedly, forming the hot wind currents that are trapped by atmospheric pressure and mountains and thus stay within the valley; such hot wind currents contribute to perpetual drought-like conditions in Death Valley and prevent much cloud formation from passing through the confines of the valley, where precipitation is in the form of a virga. Death Valley holds temperature records because it has an unusually high number of factors that lead to high atmospheric temperatures; the depth and shape of Death Valley influence its summer temperatures. The valley is a long, narrow basin 282 feet below sea level, yet is walled by high, steep mountain ranges; the clear, dry air and sparse plant cover allow sunlight to heat the desert surface. Summer nights provide little relief.
Moving masses of super-heated air blow through the valley creating high temperatures. The hottest air temperature recorded in Death Valley was 134 °F on July 10, 1913, at Greenland Ranch, the highest atmospheric temperature recorded on earth. A report of a temperature of 58 °C recorded in Libya in 1922 was determined to be inaccurate. During the heat wave that peaked with that record, five consecutive days reached 129 above; some meteorologists dispute the accuracy of the 1913 temperature measurement. The highest surface temperature recorded in Death Valley was 201.0 °F on July 15, 1972, at Furnace Creek, the highest ground surface temperature recorded on earth, as well as the only recorded surface temperature of above 200 °F. The greatest number of consecutive days with a maximum temperature of 100 °F or above was 154 days in the summer of 2001; the summer of 1996 had 40 days over 120 °F, 105 days over 110 °F. The summer of 1917 had 52 days where the temperature
California State Route 58
State Route 58 is a major east-west highway across the California Coast Ranges, the southern San Joaquin Valley, the Tehachapi Mountains, which border the southern Sierra Nevada, the Mojave Desert. It runs between its eastern terminus in Barstow, it has junctions with Interstate 5 near Buttonwillow, State Route 99 in Bakersfield, State Route 202 in Tehachapi, State Route 14 in Mojave, U. S. Route 395 at Kramer Junction. SR 58 gives good access to Edwards Air Force Base. At various points it is known as the Calf Canyon Highway, Carrisa Highway, Bakersfield-McKittrick Highway, Rosa Parks Highway, Rosedale Highway, Barstow-Bakersfield Highway, Kern County Korean War Veterans Memorial Highway, Mojave-Barstow Highway. State Route 58 between Santa Margarita and Buttonwillow is a winding mountain road through a thinly populated area. From its westernmost terminus at US 101 near Santa Margarita, a few miles north of San Luis Obispo, SR 58 heads east along the former US 101 for one mile. SR 58 heads east and up the winding mountain road, passing through thinly populated area and an intersection with SR 229.
Alternatives such as SR 46 to the north or SR 166 to the south are recommended, as much of this section of SR 58 is prohibited to truck traffic. However, this section of SR 58 does pass through the Carrizo Plain, known for its scenic beauty and geological features, including the San Andreas Fault. Route 58 takes another winding road before joining with State Route 33 in the small town of McKittrick. Route 33 splits at the north end of McKittrick before Route 58 enters another, but brief winding road. Route 58 proceeds northeast for several miles before changing to an east-west alignment and reaching Buttonwillow. A few miles Route 58 has an interchange with Interstate 5. 7 miles east of Interstate 5, Route 58 joins State Route 43 before continuing east and reaching the Bakersfield city limits. State Route 58 joins State Route 99 for about 2 miles through Bakersfield before splitting as a freeway and heading east. SR 58 enters expressway status with two at-grade intersections in the Caliente area before resuming freeway status east of Caliente.
SR 58 reaches the Tehachapi city limits and traverses the Tehachapi Pass before dropping out of the Tehachapi Mountains into the Antelope Valley at the town of Mojave. Shortly after an intersection with State Route 14, SR 58 reverts to an expressway east of Mojave before resuming freeway status bypassing North Edwards, Edwards Air Force Base, Boron. East of Boron, SR 58 reverts to one lane in each direction before an at-grade signal intersection with U. S. Route 395. 10 miles east of US 395, Route 58 resumes expressway status with two lanes in each direction until just before reaching the easternmost terminus at Interstate 15 in Barstow. State Route 58 is a freeway from its south junction with SR 99 in Bakersfield to several miles east of Mojave, except for two grade-level intersections two miles apart in the Caliente area. There is another grade level intersection east of Mojave and west of the main Edwards AFB north gate exit where California City Boulevard intersects it. Other freeway segments are bypasses of Barstow.
Except for the Boron freeway bypass, SR 58 is a four-lane expressway from just east of Boron up to the Barstow bypass segment with the exception of the portion between Boron and 5 miles east of Kramer Junction, a two-lane highway and is not yet an expressway. State Route 58 takes the southernmost route through the Sierra Nevada and allows motorists to travel between Northern California and points to the east, such as Las Vegas and Interstate 40, without having to face the extreme traffic congestion of greater Los Angeles. State Route 58 and Interstate 80 are the only freeways to cross the Sierra Nevada; the route offers an alternative to the treacherous Donner Pass to truckers traveling from the San Francisco Bay Area to points eastward. SR 58 is part of the California Freeway and Expressway System, east of I-5 is part of the National Highway System, a network of highways that are considered essential to the country's economy and mobility by the Federal Highway Administration. SR 58 is eligible for the State Scenic Highway System, but it is not designated as a scenic highway by the California Department of Transportation.
SR 58 has several names including the Blue Star Memorial Highway. The Korean War Veterans name honors the 8,120 veterans from Kern County, while the section named for Rosa Parks honors the civil rights activist; the portion of SR 58 from Barstow to Bakersfield is sometimes referred to as the Barstow–Bakersfield Highway. State Route 58 did not exist as a California sign route until 1964, although previous to 1964, it was part of California Legislative Route 58; the other part of Legislative Route 58 is California's segment of Interstate 40. Prior to 1964 the segment of State Route 58 between Bakersfield and Barstow was signed U. S. Route 466. At that time, the segment of SR 58 between State Route 33 at McKittrick and State Route 99 in Bakersfield was sig
Race and ethnicity in the United States Census
Race and ethnicity in the United States Census, defined by the federal Office of Management and Budget and the United States Census Bureau, are self-identification data items in which residents choose the race or races with which they most identify, indicate whether or not they are of Hispanic or Latino origin. The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and, "generally reflect a social definition of race recognized in this country." OMB defines the concept of race as outlined for the US Census as not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race categories include both national-origin groups. Race and ethnicity are considered separate and distinct identities, with Hispanic or Latino origin asked as a separate question. Thus, in addition to their race or races, all respondents are categorized by membership in one of two ethnic categories, which are "Hispanic or Latino" and "Not Hispanic or Latino".
However, the practice of separating "race" and "ethnicity" as different categories has been criticized both by the American Anthropological Association and members of US Commission on Civil Rights. In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government; the development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.
The OMB states, "many federal programs are put into effect based on the race data obtained from the decennial census. Race data are critical for the basic research behind many policy decisions. States require these data to meet legislative redistricting requirements; the data are needed to monitor compliance with the Voting Rights Act by local jurisdictions". "Data on ethnic groups are important for putting into effect a number of federal statutes. Data on Ethnic Groups are needed by local governments to run programs and meet legislative requirements." The 1790 United States Census was the first census in the history of the United States. The population of the United States was recorded as 3,929,214 as of Census Day, August 2, 1790, as mandated by Article I, Section 2 of the United States Constitution and applicable laws."The law required that every household be visited, that completed census schedules be posted in'two of the most public places within, there to remain for the inspection of all concerned...' and that'the aggregate amount of each description of persons' for every district be transmitted to the president."
This law along with U. S. marshals were responsible for governing the census. One third of the original census data has been lost or destroyed since documentation; the data was lost in 1790–1830 time period and included data from: Connecticut, Maryland, New Hampshire, New York, North Carolina, Rhode Island, South Carolina, Delaware, New Jersey, Virginia. Census data included the name of the head of the family and categorized inhabitants as follows: free white males at least 16 years of age, free white males under 16 years of age, free white females, all other free persons, slaves. Thomas Jefferson the Secretary of State, directed marshals to collect data from all thirteen states, from the Southwest Territory; the census was not conducted in Vermont until 1791, after that state's admission to the Union as the 14th state on March 4 of that year. There was some doubt surrounding the numbers, President George Washington and Thomas Jefferson maintained the population was undercounted; the potential reasons Washington and Jefferson may have thought this could be refusal to participate, poor public transportation and roads, spread out population, restraints of current technology.
No microdata from the 1790 population census is available, but aggregate data for small areas and their compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System. In 1800 and 1810, the age question regarding free white males was more detailed; the 1820
North American Numbering Plan
The North American Numbering Plan is a telephone numbering plan that encompasses twenty-five distinct regions in twenty countries in North America, including the Caribbean. Some North American countries, most notably Mexico, do not participate in the NANP; the NANP was devised in the 1940s by AT&T for the Bell System and independent telephone operators in North America to unify the diverse local numbering plans, established in the preceding decades. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administration, a service, procured from the private sector by the Federal Communications Commission in the United States; each participating country forms a regulatory authority that has plenary control over local numbering resources. The FCC serves as the U. S. regulator. Canadian numbering decisions are made by the Canadian Numbering Administration Consortium; the NANP divides the territories of its members into numbering plan areas which are encoded numerically with a three-digit telephone number prefix called the area code.
Each telephone is assigned a seven-digit telephone number unique only within its respective plan area. The telephone number consists of a four-digit station number; the combination of an area code and the telephone number serves as a destination routing address in the public switched telephone network. For international call routing, the NANP has been assigned the international calling code 1 by the International Telecommunications Union; the North American Numbering Plan conforms with ITU Recommendation E.164, which establishes an international numbering framework. From its beginnings in 1876 and throughout the first part of the 20th century, the Bell System grew from local or regional telephone systems; these systems expanded by growing their subscriber bases, as well as increasing their service areas by implementing additional local exchanges that were interconnected with tie trunks. It was the responsibility of each local administration to design telephone numbering plans that accommodated the local requirements and growth.
As a result, the Bell System as a whole developed into an unorganized system of many differing local numbering systems. The diversity impeded the efficient operation and interconnection of exchanges into a nationwide system for long-distance telephone communication. By the 1940s, the Bell System set out to unify the various numbering plans in existence and developed the North American Numbering Plan as a unified, systematic approach to efficient long-distance service that did not require the involvement of switchboard operators; the new numbering plan was accepted in October 1947, dividing most of North America into eighty-six numbering plan areas. Each NPA was assigned a numbering plan area code abbreviated as area code; these codes were first used by long-distance operators to establish long-distance calls between toll offices. The first customer-dialed direct call using area codes was made on November 10, 1951, from Englewood, New Jersey, to Alameda, California. Direct distance dialing was subsequently introduced across the country.
By the early 1960s, most areas of the Bell System had been converted and DDD had become commonplace in cities and most larger towns. In the following decades, the system expanded to include all of the United States and its territories, Canada and seventeen nations of the Caribbean. By 1967, 129 area codes had been assigned. At the request of the British Colonial Office, the numbering plan was first expanded to Bermuda and the British West Indies because of their historic telecommunications administration through Canada as parts of the British Empire and their continued associations with Canada during the years of the telegraph and the All Red Line system. Not all North American countries participate in the NANP. Exceptions include Mexico, Saint Pierre and Miquelon, the Central American countries and some Caribbean countries; the only Spanish-speaking state in the system is the Dominican Republic. Mexican participation was planned, but implementation stopped after three area codes had been assigned, Mexico opted for an international numbering format, using country code 52.
The area codes in use were subsequently withdrawn in 1991. Area code 905 for Mexico City, was reassigned to a split of area code 416 in the Greater Toronto Area. Dutch-speaking Sint Maarten joined the NANP in September 2011, receiving area code 721; the NANP is administered by the North American Numbering Plan Administration. Today, this function is overseen by the Federal Communications Commission, which assumed the responsibility upon the breakup of the Bell System; the FCC solicits private sector contracts for the role of the administrator. The service was provided by a division of Lockheed Martin. In 1997, the contract was awarded to Neustar Inc.. In 2012, the contract was renewed until 2017. In 2015, the contract beginning 2017 was granted to Ericsson; the vision and goal of the architects of the North American Numbering Plan was a system by which telephone subscribers in the United States and Canada could themselves dial and establish a telephone call to any other subscriber wi
Antelope Valley is located in northern Los Angeles County and the southeast portion of Kern County and constitutes the western tip of the Mojave Desert. It is situated between the San Gabriel Mountains; the valley was named for the pronghorns that roamed there until they were all but eliminated in the 1880s by hunting, or resettled in other areas. The principal cities in the Antelope Valley are Lancaster; the Antelope Valley comprises the western tip of the Mojave Desert, opening up to the Victor Valley and the Great Basin to the east. Lying north of the San Gabriel Mountains and southeast of the Tehachapis, this desert ecosystem spans 2,200 square miles. Precipitation in the surrounding mountain ranges contributes to groundwater recharge; the Antelope Valley is home to a wide range of animals. This includes hundreds of plants such as the California Juniper, Joshua tree, California Scrub Oak and wildflowers, notably the California poppy. Winter brings much-needed rain which penetrates the area's dry ground, bringing up native grasses and wildflowers.
Poppy season depends on the precipitation, but a good bloom can be killed off by the unusual weather in the late winter and early spring months. The Antelope Valley gets its name from its history of pronghorn grazing in large numbers. In 1882-85, the valley lost 30,000 head of antelope half of the species for which it was named. Unusually heavy snows in both the mountains and the valley floor drove the antelope toward their normal feeding grounds in the eastern part of the valley. Since they would not cross the railroad tracks, many of them starved to death; the remainder of these pronghorn were hunted for their fur by settlers. Once abundant, they migrated into the Central Valley. A drought in the early 1900s caused a scarcity in their main food source. Now the sighting of a pronghorn is rare, although there are still a small number in the western portion of the valley. Human water use in the Antelope Valley depends on pumping of groundwater from the valley's aquifers and on importing additional water from the California Aqueduct.
Long-term groundwater pumping has lowered the water table, thereby increasing pumping lifts, reducing well efficiency, causing land subsidence. While aqueducts supply additional water that meets increasing human demand for agricultural and domestic uses, diversion of water from the Sacramento-San Joaquin River Delta in northern California has caused and causes adverse environmental and social effects in the delta: "Over decades, competing uses for water supply and habitat have jeopardized the Delta’s ability to meet either need. All stakeholders agree the estuary is in trouble and requires long-term solutions to ensure reliable, quality water supplies and a healthy ecosystem." The Antelope Valley's population growth and development place considerable stress on the local and regional water systems. According to David Leighton of the United States Geological Survey: "A deliberate management effort will be required to meet future water demand in the Antelope Valley without incurring significant economic and environmental costs associated with overuse of the ground-water resource."
The first peoples of the Antelope Valley include the Kawaiisu, Kitanemuk and Tataviam. Europeans first entered during the colonization of North America. Father Francisco Garces, a Spanish Franciscan friar, is believed to have traveled the west end of the valley in 1776; the Spanish established El Camino Viejo through the western part of the valley between Los Angeles and the missions of the San Francisco Bay in the 1780s. By 1808, the Spanish had moved the native people out into missions. Jedediah Smith came through in 1827, John C. Fremont made a scientific observation of the valley in 1844. After Fremont's visit the 49ers crossed the valley via the Old Tejon Pass into the San Joaquin Valley on their way to the gold fields. A better wagon road, the Stockton – Los Angeles Road route to Tejon Pass, followed in 1854. Stagecoach lines across the southern foothills came through the valley along this wagon road, were the preferred method for travelers before the coming of the Southern Pacific Railroad in 1876.
The rail service linking the valley to the Central Valley and Los Angeles started its first large influx of white settlers, farms and towns soon sprouted on the valley floor. The aircraft industry took hold in the valley at Plant 42 in 1952. Edwards AFB called Muroc Army Air Field, was established in 1933. In recent decades the valley has become a bedroom community to the Greater Los Angeles area. Major housing tract development and population growth took off beginning in 1983, which has increased the population of Palmdale around 12 times its former size as of 2006. Neighboring Lancaster has increased its population since the early 1980s to around three times its former level. Major retail has followed the population influx, centered on Palmdale's Antelope Valley Mall; the Antelope Valley is home to over 475,000 people. Non-Hispanic whites make up 48% of the population of the Antelope Valley and form a majority or plurality in most of its cities and towns. Hispanics are the next largest group, followed by Asian Americans.
Some long-term residents living far out in the desert have been cited by Los Angeles County's nuisance abatement teams for code violations, forcing residents to either make improvements or move. One of the properties is a church building, used as a filming location for Kill Bill; the code enforcers have arrived on some of their visits in SWAT team formats. Edwards Air Force Base lie
