| Location | class 3[3] |
Mount Wilson is the
bearing 12°) of the Town of Rico in Dolores County, Colorado, United States.[a][1][2] Mount Wilson should not be confused with the lower Wilson Peak
nearby.
The peak was named for
Hayden Survey. He was in the first ascent party, which climbed the peak on September 13, 1874, via the south ridge (a difficult route, not often climbed today).[4]
Climbing
Mount Wilson is ranked among the top ten hardest of the Colorado
crampons
recommended. Scrambling on rock then leads to the summit.
A popular, though long, outing for expert climbers is the mile-long ridge connecting Mount Wilson to
rappelling
.
Geology and history
Mount Wilson, and the rest of the San Miguel Mountains, are made up of a large, irregular
intrusion.[6]
The Mount Wilson region became the site of intense mining activity, particularly for silver, in the early 1880s. The most famous of these mines was the Silver Pick Mine, which gave its name to Silver Pick Basin, just north of Navajo Basin.
Glaciers and permafrost
Mount Wilson contains four small
Sierra Nevada in California. These descend to 3,887 metres (12,753 ft). None of the glaciers have ever been named, and it has never been investigated whether they are presently active.[7] At least nine rock glaciers, composed of alpine permafrost, exist on the northern slope of the mountain, extending down to around 10,000 feet (3,050 m), although the lower limit of permafrost is more typically around 11,500 feet (3,500 m).[8]
During the Pleistocene glaciers were much more extensive than today, covering the whole summit plateau[9] In glaciations previous to the Wisconsinian, it is generally thought that summit ice caps were even more extensive and joined to form the "San Miguel Glacier" with icecaps in the San Juan Mountains.[10]
