Geography of Colorado
The Rocky Mountains within Colorado contain 54 peaks that are 14,000 feet (4270 m) or higher, known as fourteeners. The mountains are timbered with conifers and aspen to the tree line, at an elevation of about 12,000 feet (3,650 m) in southern Colorado to about 10,500 feet (3,200 m) in northern Colorado; above this only alpine vegetation grows. The Rockies are snow-covered only in the winter; most snow melts by mid-August with the exception of a few small glaciers. The Colorado Mineral Belt, stretching from the San Juan Mountains in the southwest to Boulder and Central City on the front range, contains most of the historic gold and silver mining districts of Colorado.
Mount Cromwell
In 2005, Bill Corbett, author of "The 11,000ers of the Canadian Rockies," climbed to the top of Mount Cromwell. At the summit, his GPS registered 11,006 feet. So perhaps Mount Cromwell should be included in the list of the Canadian Rocky Mountains that are over 11,000 feet in elevation.
