Mount Sneffels Wilderness

The United States Congress designated the Mount Sneffels Wilderness in 1980, and it now has a total of 16,566 acres. Mount Sneffels, a 14,150-foot intrusion of igneous rock on the eastern verge of this area, stands higher than any other point in the Wilderness. Members of the Hayden Survey purportedly named the peak after the Icelandic mountain in Jules Verne's "Journey to the Center of the Earth." Sneffels is the Nordic word for snowfield. Westward stretches a sheer vertical world of sharp ridges, icy slopes, and ragged peaks. It makes for dangerous climbing typical of the San Juan Mountains, sometimes called America's Switzerland, a land of unsurpassed mountain drama.

Precipitation totals about 20 inches a year. The dotted line is average snowfall, about 131 inches a year on the same inches scale. The station sits about 3,100 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
