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.
List of mountains of Alberta
The peaks of the Canadian Rockies are majestic, many of them reaching a height of more than three kilometres above sea level. Alberta's southwestern boundary is traced on the Continental Divide, along the high ranges of the Rocky Mountains, and many peaks are located on the Alberta–British Columbia border. The peak of Mount Columbia, within Jasper National Park, is the highest point in Alberta, second highest in the Canadian Rockies and 28th highest in Canada.
