The Eastern Plains of Colorado refers to a region of the U. S. state of Colorado east of the Rocky Mountains and east of the population centers of the Front Range. The Eastern Plains are part of the High Plains, which are the westernmost portion of the Great Plains; the region is characterized by rolling plains, divided by the South Platte River and Arkansas River valleys. There are several deciduous forests, buttes, a few large natural lakes and rivers throughout the region; the Eastern Plains rise from 3,400 feet at the eastern border of Colorado with Kansas, where the Arkansas River leaves the state, to 7,500 feet east of the Denver Basin. Most of the Eastern Plains region lies within Colorado's 4th congressional district; the Eastern Plains receive little rainfall. Much of the area relies on irrigation to survive. Summers are hot and dry bringing thunderstorms, which are severe, to the area, with some forming landspouts and tornadoes. Eastern Colorado winters are dry, with significant snowfalls and icy conditions.
Temperatures can sometimes fall to -40 to -30 degrees Fahrenheit in extreme cold waves, although this is rare. Eastern Colorado was once home to many Native American tribes; the Plains Indians that lived in the region included the Arapahoe, Kiowa and Sioux. The Ute people formally ruled all over central and western Colorado, onto the eastern plains as well; the Comanche once ruled all over southeastern Colorado, the Jicarilla Apache ruled in southeastern Colorado as well. In 1541, the Spanish came to the area now known as the south eastern portion of Colorado, in search of gold after hearing rumors in Mexico city. Not having found any gold, the Spanish left the area untouched. During the late 17th and 18th century Spain and France claimed southeastern Colorado. However, nobody settled the land. In 1803 the United States gained possession of the land east of Rocky Mountains with the Louisiana Purchase. Zebulon M. Pike was sent by the federal government to lay out the boundary lines of territory in 1806.
This expedition investigated the area now known as Colorado Springs. The prominent mountain in the area was named Pike's Peak after Pike, the leading commander of the exploration. There were multiple expeditions sent to lay out and explore the territory throughout the early 1800s; this created multiple trading posts with fur trades attracting many backcountry adventurers. There was still no permanent settlement created until after the conclusion of the Mexican War in 1848. San Luis was founded on the Culebra River in 1851. Spanish-speaking settlers who had moved north from New Mexico founded it. San Luis was shortly followed by settlements of San Acacio and Guadalupe; the Eastern Colorado plains are among the most sparsely populated areas in the continental United States. Some of the region, with the exception of comparatively urban areas like Sterling, is experiencing depopulation, which in some areas began with the influenza pandemic of 1918 and agricultural price collapses after World War I.
The Dust Bowl further accelerated this outmigration. Kiowa County demonstrates its associated effects. Both the Pawnee National Grasslands and Comanche National Grasslands are located in the Eastern Plains, they are composed of marginal farmlands that were withdrawn from agriculture and consolidated under federal control beginning in the Dust Bowl. Eastern Colorado is farmland, with many small farming communities; the major cash crops are corn, hay and soybeans. There is significant livestock farming and poultry farming, including chicken for meat and eggs, turkey farming. Most of the towns in the region have grain elevators and prominent water towers. Over 90% of the farms in Eastern Colorado are family farms. In Eastern Colorado most small towns have their own schools and sports teams, but in some parts where depopulation has been the worst, a single school is shared among surrounding towns. There are a number of schools serving students in grades K–12 run by religious groups or public school districts.
Eastern Colorado is one of the few remaining places in the United States with still operating one-room school houses. The most prominent religion in Eastern Colorado is Christianity, with Roman Catholicism the largest denomination. Eastern Colorado roads span the gamut from paved roads to gravel roads to dirt roads; the unpaved roads are county or local roads that do not receive enough traffic to be paved. Some of the major paved roads include: Interstate 76 Interstate 70 U. S. Highway 6 U. S. Highway 24 U. S. Highway 36 U. S. Highway 40 U. S. Highway 50 U. S. Highway 160 U. S. Highway 287 U. S. Highway 350 U. S. Highway 385 State Highway 10 State Highway 11 State Highway 36 State Highway 59 State Highway 71 State Highway 86 State Highway 94 State Highway 96 Shortgrass prairie Buffalo Commons
A Kensington Security Slot is part of an anti-theft system designed in the early 1990s and patented by Kryptonite in 1999–2000, assigned to Schlage in 2002, since 2005 owned and marketed by Kensington Computer Products Group, a division of ACCO Brands. The system consists of a small, metal-reinforced hole found on small or portable computers and electronics equipment such as laptops, computer monitors, desktop computers, gaming consoles, video projectors, combined with a metal anchor attached to a rubberized metal cable secured with a key or combination lock; the end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a heavy table or other similar equipment. The hole is found in most laptops, although a lock for it is not included; the slot is located so that installing a lock will prevent the removal of a valuable subcomponent, such as a rechargeable battery or a memory module. The Kensington slot may be marked with a small icon that looks like a padlock with a capital "K", or the slot may be unlabelled.
Kensington locks are not designed to be an impervious protection measure. Because most computer equipment cases are made of plastic or thin metal, the lock can be torn out, though not without doing significant visible damage to the case; the cable itself can be cut if an individual has a wire cutter or bolt cutter sufficiently strong to cut through the cable material, which will vary between different brands of cable. The Kensington type locks are useful to discourage quick grab-and-run thefts of equipment from casually supervised locations such as coffee shops, but cannot prevent the removal of equipment secured in an unattended location; the key is a cylindrical type, but there are versions which use a traditional flat key. There are versions of the lock that use a numeric combination instead of a key. Several manufacturers offer similar locking mechanisms, they attach to a popular port, such as the VGA or printer port, have special screws to secure locks in place. Official website
