Geography of Colorado

The geography of the state of Colorado is diverse, encompassing both rugged mountainous terrain, vast plains, desert lands, desert canyons, and mesas. The state of Colorado is defined as the geospherical rectangle that stretches from 37°N to 41°N latitude and from 102°03'W to 109°03'W longitude (25°W to 32°W from the Washington Meridian). Colorado is one of only three U.S. states (with Wyoming and Utah) that have only lines of latitude and longitude for boundaries.

The summit of Mount Elbert at 14,440 feet (4,401.2 m) elevation in Lake County is the state's highest point and the highest point in the Rocky Mountains of North America. Colorado has approximately 550 mountain peaks that exceed 4000 meters elevation. Colorado is the only U.S. state that lies entirely above 1000 meters elevation. The state's lowest elevation is 3,317 feet (1,011 m) at the point on the eastern boundary of Yuma County where the Arikaree River flows into the state of Kansas.

To the east of the Rocky Mountains in Colorado are the Colorado Eastern Plains/High Plains, the section of the Great Plains within Colorado at elevations ranging from 3,500 to 7,000 feet (1,100 to 2,100 metres). The Midwest states of Kansas and Nebraska border Colorado to the east and northeast.
