The Mount Shasta Wilderness is a 38,200-acre (155 km2) federally designated wilderness area located 5 miles (8.0 km) east of Mount Shasta City in northern California. The US Congress passed the 1984 California Wilderness Act that set aside the Mount Shasta Wilderness. The US Forest Service is the managing agency as the wilderness is within the Shasta-Trinity National Forest. The area is named for and is dominated by the Mount Shasta Volcano which reaches a traditionally quoted height of 14,162 feet (4,317 m) above sea level, but official sources give values ranging from 14,104 feet (4,299 m) from one USGS project, to 14,179 feet (4,322 m) via the NOAA. Mount Shasta is one of only two peaks in the state over 14,000 feet (4,300 m) outside the Sierra Nevada Mountain Range. The other summit is White Mountain Peak in the Great Basin of east-central California.
Being a high, solitary and very large mountain with a base diameter of 17 miles (27 km), Mount Shasta can create its own weather patterns which hikers must be aware of. Also, falling rocks are a major danger above timberline. The best time of year for hiking Mount Shasta is June and July, when routes are still snow-covered. Although there is no designated trail to the summit, many cross-country routes ascend to the mountaintop and all require experience in traversing ice and snow.
There are ten trailheads giving access to the wilderness and several short trails leading up the slopes of Mount Shasta with the so-called Shasta Summit Trail (or Avalanche Gulch) being the most popular. This trail, although the "easiest" of the routes, still requires the use of ice axe and crampons. There are four major glaciers and three smaller glaciers radiating from the summit in addition to lava flows on the northern flank composed of andesite and basalt.
Flora and Fauna
Forested areas include pure stands of red fir as well as mixed conifer forests of white fir, Douglas-fir, Sugar Pine, incense cedar and at higher elevations, western white pine. The lava flows on the northeast flank have mountain mahogany and Juniper. Underbrush consists of pinemat manzanita, greenleaf manzanita, tanoak, chinquapin, and snowbrush. From 8,000 feet (2,400 m) to timberline are krummholz forms of whitebark pine. Wildlife include the ubiquitous black bear, coyote, ground squirrel, deer, Golden eagles, prairie falcons and red-tail hawks.
Sierra Club Camp
The Sierra Club maintains a private 720-acre (2.9 km2) parcel called Horse Camp within the wilderness. It is used as a base camp for summit attempts, and offers a shelter called the Shasta Alpine Lodge, dedicated in 1923 and built from surrounding volcanic rock and Shasta red fir wood. Horse Camp is staffed during the climbing season from May to September, has a seasonal spring for water and is a traditional destination of many elementary school trips from Siskiyou County schools. Also at Horse Camp is the half-mile-long Olberman Causeway, a stone walkway built in the 1920s by the first caretaker, Mac Olberman from rocks of the surrounding area.
