[Hot air balloon over Boulder Co. Photo: Let Ideas Compete] Boulder County claimed a population of 294,567 in the 2010 census. Both the county seat and most populous town are Boulder.
Named for Boulder City and Boulder Creek (due to the plentiful boulders found therein, of course), Boulder County was one of the original 17 counties created by the Territory of Colorado on November 1, 1861.
National protected areas include Arapaho National Forest, Roosevelt National Forest, Indian Peaks Wilderness, and James Peak Wilderness. Rocky Mountain National Park is found in Boulder County, northwest of the city of Boulder.
