About the map
This Colorado county map displays its 64 counties. For example, Denver, El Paso, and Arapahoe are the most populated in the state of Colorado.
In terms of size, Las Animas, Moffat, and Weld County are the largest in area. But Broomfield, Gilpin, and Denver County are some of the smallest counties in all of the United States.
Mount Elbert is one of the highest summits in Colorado at 14,440′ and is part of the Rocky Mountains. This summit is in Lake County, confusingly just south of Summit County. As people pile rocks on Mount Massive, this summit also contends as one of the highest. Similar to Mount Elbert, it’s also part of Lake County.
