The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Alpine Visitor Center
Rocky Mountain National Park's Alpine Visitor Center is located at 11,796 feet above sea level at Fall River Pass, one mile west of the highest point on Trail Ridge Road and four miles east of the Continental Divide at Milner Pass in the U. S. state of Colorado. It is the highest visitor center in the National Park System; the Alpine Visitor Center includes restrooms, exhibits on the alpine tundra ecosystem, a gift shop operated by the park's non-profit partner organization, the Rocky Mountain Conservancy. The visitor center opens around Memorial Day and closes around mid-October due to snow and the extreme winter environment. In mid-summer, the visitor center is usually accessible by Old Fall River Road, a 9-mile dirt road open to one-way, uphill vehicle traffic. Views from the Alpine Visitor Center include the Mummy Range, the Fall River Valley, Trail Ridge to the east and the Never Summer and Medicine Bow ranges to the west and north. Hiking opportunities include the 1/4-mile round-trip Alpine Ridge Trail referred to as "Huffer's Hill," and the 8-mile round-trip Ute Trail to Milner Pass.
Park Rangers provide park interpretive programs on the alpine tundra. Additional gift and food services at Fall River Pass are provided at the concession-operated "Trail Ridge Store and Cafe."
Longs Peak is a high and prominent mountain summit in the northern Front Range of the Rocky Mountains of North America. The 14,259-foot fourteener is located in the Rocky Mountain National Park Wilderness, 9.6 miles southwest by south of the Town of Estes Park, United States. Longs Peak is the northmost "fourteener" in the Rocky Mountains and the highest point in Boulder County and Rocky Mountain National Park; the mountain was named in honor of explorer Stephen Harriman Long and is featured on the Colorado state quarter. Longs Peak can be prominently seen from Longmont, Colorado, as well as from most of the northern Front Range Urban Corridor. Longs Peak is one of the most prominent mountains in Colorado, rising 9,000 feet above the western edge of the Great Plains; the peak is named for Major Stephen Long, said to be the first to spot the great mountains on behalf of the U. S. Government on June 30, 1820. Together with the nearby Mount Meeker, with an elevation of 13,911 feet, the two are sometimes referred to as the Twin Peaks.
As the only fourteener in Rocky Mountain National Park, the peak has long been of interest to climbers. The easiest route is not "technical" during the summer season, it was first used by pre-Columbian indigenous people collecting eagle feathers. The first recorded ascent was in August 23, 1868 by the surveying party of John Wesley Powell via the south side; the East Face of the mountain is 1,675 feet steep and is surmounted by a 1,000 feet steep sheer cliff known as "The Diamond". Another famous profile belongs to Longs Peak: to the southeast of the summit is a series of rises which, when viewed from the northeast, resembles a beaver. In 1954 the first proposal made to the National Park Service to climb The Diamond was met with an official closure, a stance not changed until 1960; the Diamond was first ascended by Dave Rearick and Bob Kamps that year, by a route that would come to be known as D1. This route would be listed in Allen Steck and Steve Roper's influential book Fifty Classic Climbs of North America.
The easiest route on the face is the Casual Route, first climbed in 1977. It has since become the most popular route up the wall; the oldest person to summit Longs Peak was Rev. William "Col. Billy" Butler, who climbed it on September 2, 1926, his 85th birthday. In 1932, Clerin "Zumie" Zumwalt summited Longs Peak 53 times; the record number of ascents to the summit of Longs Peak is 428, by Jim Detterline. Jim was a rescue Ranger in Rocky Mountain National Park. On October 23, 2016, he died in an accident while solo climbing. Jim rescued over 1,000 people in the mountains of Rocky Mountain National Park and he received the U. S. Interior Department's Valor Award, he earned the title,"Mr. Longs Peak". Http://www.alpinist.com/doc/web16f/newswire-detterline-obit The record number of ascents to the Summit for a woman is held by Lisa Foster who, in August 2015, had climbed Longs Peak 73 times and in every month of the year. Http://www.estesparknews.com/featured_articles/article_acd9974e-46b6-11e5-830f-b7212af15eec.html On June 6, 2016, a group of US Special Forces were rescued after members of the team suffered from altitude sickness.
Longs Peak has one remaining glacier named Mills Glacier. The glacier is located around 12,800 feet at the base of the Eastern Face, just above Chasm Lake. A permanent snowfield, called The Dove, is located north of Longs Peak. Longs Peak is one of fewer than 50 mountains in Colorado that have a glacier. Trails that ascend Longs Peak include the East Longs Peak Trail, the Longs Peak Trail, the Keyhole Route, Clark's Arrow and the Shelf Trail. Only some technical climbing is required to reach the summit of Longs Peak during the summer season, which runs from mid July through early September. Outside of this window the popular "Keyhole" route is still open, it is one of the most difficult Class 3 fourteener scrambles in Colorado. The hike from the trailhead to the summit is 8.4 miles each way, with a total elevation gain of 4,875 feet. Most hikers begin before dawn in order to reach the summit and return below the tree line before frequent afternoon thunderstorms bring a risk of lightning strikes.
The most difficult portion of the hike begins at the Boulder Field, 6.4 miles into the hike. After scrambling over the boulders, hikers reach the Keyhole at 6.7 miles. The following quarter of a mile involves a scramble along narrow ledges, many of which may have nearly sheer cliffs of 1,000 feet or more just off the edge; the next portion of the hike includes climbing over 600 vertical feet up the Trough before reaching the most exposed section of the hike, the Narrows. Just beyond the Narrows, the Notch signifies the beginning of the Homestretch, a steep climb to the football field-sized, flat summit, it is possible to camp out overnight in the Boulder Field which makes for a less arduous two-day hike, although this is exposed to the elements. Fifty-eight people have died climbing or hiking Longs Peak. According to the National Park Service, two people, on average, die every year attempting to climb the mountain. Less experienced mountaineers are encouraged to use a guide for this summit to mitigate risk and increase the probability of a summit.
For hikers who do not wish to climb to the summit, there are less-involved hikes on the peak as well. Peacock Po
Mount Chiquita is a mountain summit in the Mummy Range of the Rocky Mountains of North America.

Colorado is a state of the Western United States encompassing most of the southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. It is the 8th most extensive and 21st most populous U. S. state. The estimated population of Colorado was 5,695,564 on July 1, 2018, an increase of 13.25% since the 2010 United States Census. The state was named for the Colorado River, which early Spanish explorers named the Río Colorado for the ruddy silt the river carried from the mountains; the Territory of Colorado was organized on February 28, 1861, on August 1, 1876, U. S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state one century after the signing of the United States Declaration of Independence. Colorado is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south, Utah to the west, touches Arizona to the southwest at the Four Corners.
Colorado is noted for its vivid landscape of mountains, high plains, canyons, plateaus and desert lands. Colorado is part of the western and southwestern United States, is one of the Mountain States. Denver is most populous city of Colorado. Residents of the state are known as Coloradans, although the antiquated term "Coloradoan" is used. Colorado is notable for its diverse geography, which includes alpine mountains, high plains, deserts with huge sand dunes, deep canyons. In 1861, the United States Congress defined the boundaries of the new Territory of Colorado by lines of latitude and longitude, stretching from 37°N to 41°N latitude, from 102°02'48"W to 109°02'48"W longitude. After 158 years of government surveys, the borders of Colorado are now defined by 697 boundary markers and 697 straight boundary lines. Colorado and Utah are the only states that have their borders defined by straight boundary lines with no natural features; the southwest corner of Colorado is the Four Corners Monument at 36°59'56"N, 109°2'43"W.
This is the only place in the United States where four states meet: Colorado, New Mexico and Utah. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado and the Rocky Mountains of North America. Colorado is the only U. S. state that lies above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County and into Cheyenne County, Kansas, is the lowest point in Colorado at 3,317 feet elevation; this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than half of Colorado is flat and rolling land. East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from 3,350 to 7,500 feet; the Colorado plains are prairies but include deciduous forests and canyons. Precipitation averages 15 to 25 inches annually. Eastern Colorado is presently farmland and rangeland, along with small farming villages and towns.
Corn, hay and oats are all typical crops. Most villages and towns in this region boast both a grain elevator. Irrigation water is available from subterranean sources. Surface water sources include the South Platte, the Arkansas River, a few other streams. Subterranean water is accessed through artesian wells. Heavy use of wells for irrigation caused underground water reserves to decline. Eastern Colorado hosts considerable livestock, such as hog farms. 70% of Colorado's population resides along the eastern edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado; the "Front Range" includes Denver, Fort Collins, Castle Rock, Colorado Springs, Pueblo and other townships and municipalities in between. On the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction and Montrose.
The Continental Divide of the Americas extends along the crest of the Rocky Mountains. The area of Colorado to the west of the Continental Divide is called the Western Slope of Colorado. West of the Continental Divide, water flows to the southwest via the Colorado River and the Green River into the Gulf of California. Within the interior of the Rocky Mountains are several large parks which are high broad basins. In the north, on the east side of the Continental Divide is the North Park of Colorado; the North Park is drained by the North Platte River, which flows north into Nebraska. Just to the south of North Park, but on the western side of the Continental Divide, is the Middle Park of Colorado, drained by the Colorado River; the South Park of Colorado is the region of the headwaters of the South Platte River. In southmost Colorado is the large San Luis Valley, where the headwaters of the Rio Grande are located; the valley sits between the Sangre De Cristo Mountains and San Juan Mountains, consists of large desert lands that run into the mountains.
The Rio Grande drains due south into New Mexico and Texas. Across the Sangre de Cristo Range to the east of the S
Heritage Documentation Programs
Heritage Documentation Programs is a division of the U. S. National Park Service responsible for administering the Historic American Buildings Survey, Historic American Engineering Record, Historic American Landscapes Survey; these programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, written reports, are archived in the Prints and Photographs Division of the Library of Congress. In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency, it was founded as a constructive make-work program for architects and photographers left jobless by the Great Depression. Guided by field instructions from Washington, D. C. the first HABS recorders were tasked with documenting a representative sampling of America's architectural heritage. By creating an archive of historic architecture, HABS provided a database of primary source material and documentation for the then-fledgling historic preservation movement.
Earlier private projects included the White Pine Series of Architectural Monographs, many contributors to which joined the HABS program. Notable HABS photographers include Jack Boucher; the Historic American Engineering Record program was founded on January 10, 1969, by NPS and the American Society of Civil Engineers. HAER documents historic mechanical and engineering artifacts. Since the advent of HAER, the combined program is called "HABS/HAER". Today much of the work of HABS/HAER is done by student teams during the summer, or as part of college-credit classwork. Eric DeLony headed HAER from 1971 to 2003. In October 2000, NPS and the American Society of Landscape Architects established a sister program, the Historic American Landscapes Survey, to systematically document historic American landscapes. A predecessor, the Historic American Landscape and Garden Project, recorded historic Massachusetts gardens between 1935 and 1940; that project was funded by the Works Progress Administration, but was administered by HABS, which supervised the collection of records.
The permanent collection of HABS/HAER/HALS are housed at the Library of Congress, established in 1790 as the replacement reference library of the United States Congress. It has since been expanded to serve as the National Library of the United States. S. publishers are required to deposit a copy of every copyrighted and published work, book monograph and magazine. As a branch of the United States Government, its created works are in the public domain in the US. Many images and documents are available through the Prints and Photographs Online Catalog, including proposed and existing structures.
