Mount Shasta

A 4,322-metre stratovolcano in the southern Cascade Range of northern California, the second-highest peak in the Cascades after Rainier and the highest in California south of the Sierra Nevada. Shasta is a compound volcano — multiple overlapping cones — and the upper mountain is a complex of summit ridges rather than a single peak. The summit itself, Shasta's main summit, is 4,322 metres. Shastina, the secondary summit at 3,758 metres, is a separate volcanic cone on the western flank. The mountain is sacred to the Indigenous peoples of the surrounding region, including the Wintu, Karuk, Modoc, and Shasta nations.

The first ascent in the European-American mountaineering tradition came in 1854 by Captain Elias Pearce of the U.S. Army. The summit had been reached previously by Indigenous climbers in religious context; the Wintu name for the mountain, Bohem Puyuk, is associated with creation narratives in which the mountain serves as the residence of the creator. Modern climbing on Shasta has the John Muir route, the Avalanche Gulch route, and the more technical Hotlum-Bolam Ridge as established lines. The standard Avalanche Gulch route involves sustained snow and ice climbing, a steep upper section called the Red Banks that requires kicking steps in firm snow, and a final summit dome that holds altitude challenges.

The fatality rate on Shasta has been moderate. Most accidents have involved exposure on storm days, falls in the upper Avalanche Gulch sections, and altitude problems in climbers who have rapidly ascended from sea level. The peak receives approximately 6,000 summit attempts per year. The climbing season is May through August, though winter ascents are made by experienced parties.

Shasta has, in recent decades, become a destination for spiritual tourism alongside its mountaineering use — a development that has occasionally produced friction with the Indigenous communities whose religious tradition predates the climbing era. The peak remains primarily a climbing objective, but the mountain holds meaning for multiple constituencies whose relationships to the place have not always aligned.
