Mt. Shasta Wilderness

Even first-time visitors to the area have no trouble identifying Mount Shasta. Dominating the landscape for several hundred miles in all directions, the mountain looms 14,179 feet, a beautiful snow-cloaked massif, second only to Mount Rainier in height among the famous Cascade Range volcanoes. Although the last documented eruption occurred in 1786, geologists classify Shasta as an active volcano. Most of the Wilderness lies on the upper slopes of the mountain. Below the seven glaciers that drape the mountain's slopes, you'll find a land of scenic wonder: ancient lava flows, a hot sulphur spring, waterfalls tumbling down deep canyons cut through rugged buttes.

The line is the average temperature and the bars are average precipitation at Mt Shasta, 9 miles from the center point at 3,613 feet, station USC00045983 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 43 inches a year. The dotted line is average snowfall, about 89 inches a year on the same inches scale. The station sits about 7,800 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.
