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 Sopris
Mount Sopris dominates the skyline of Carbondale and the lower Roaring Fork Valley, serving as an unofficial symbol of the area. It is prominently visible from State Highway 82 in the vicinity of Carbondale. In terms of local relief, it is one of the largest peaks in the state of Colorado. For example, West Sopris rises 6,400 ft (1,905 m) above the valley to the west in only 2.7 mi (4 km). (One can compare this to the corresponding vertical rise of the more well-known Maroon Peak in the heart of the Elks: it rises only about 4,300 ft (1,310 m), at best, in the same horizontal distance.) In fact a vertical rise of over 6,000 feet in less than 3 miles is rare and impressive anywhere in the contiguous United States.
