The geography of the U.S. State of Colorado is diverse, encompassing both rugged mountainous terrain, vast plains, desert lands, desert canyons, and mesas. Colorado is a landlocked U.S. state. In 1861, the United States Congress defined the boundaries of the new Territory of Colorado exclusively by lines of latitude and longitude, stretching from 37°N to 41°N latitude, and from 102°02'48"W to 109°02'48"W longitude. Starting in 1868, official surveys demarcated the boundaries, deviating from the parallels and meridians in several places. Later surveys attempted to correct some of these mistakes but in 1925 the U.S. Supreme Court affirmed that the earlier demarcation was the official boundary. The borders of Colorado are now officially defined by 697 boundary markers connected by straight boundary lines. Colorado, Wyoming, and Utah are the only states that have their borders defined solely 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, Arizona, and Utah.

The Sangre de Cristo Land Grant in the San Luis Valley of southern Colorado and northern New Mexico consists of 1,000,000 acres (4,000 km2) of mostly arid land. It was awarded by the government of New Mexico to the Beaubien family in 1843. The land grant was originally settled by Hispanics from New Mexico. Since the incorporation of the area of the grant into the United States in 1848, legal disputes between the descendants of the Hispanic settlers and Anglo ranchers about ownership of and access to some of the land in the grant area have been frequent and continued into the 21st century.
