Description

Mount Shasta is connected to its satellite cone of Shastina, and together they dominate the landscape. Shasta rises abruptly to tower nearly above its surroundings. On a clear winter day, the mountain can be seen from the floor of the Central Valley to the south. The mountain has attracted the attention of poets, authors, and presidents. The mountain consists of four overlapping dormant volcanic cones that have built a complex shape, including the main summit and the prominent and visibly conical

in the area held that Mount Shasta is inhabited by the Spirit of the Above-World, Skell, who descended from heaven to the mountain's summit at the request of a Klamath chief. Skell fought with Spirit of the Below-World, Llao, who resided at Mount Mazama by throwing hot rocks and lava, probably representing the volcanic eruptions at both mountains. Italian settlers arrived in the early 1900s to work in the mills as stonemasons and established a strong Catholic presence in the area.

Volcanic status

During the last 10,000 years, Mount Shasta has erupted an average of every 800 years, but in the past 4,500 years the volcano has erupted an average of every 600 years. USGS seismometers and GPS receivers operated by UNAVCO form the monitoring network for Mount Shasta. The volcano has been relatively quiet for at least the past 15 years, with only a handful of small magnitude earthquakes and no demonstrable ground deformation. Although geophysically quiet, periodic geochemical surveys indicate that volcanic gas emanates from a fumarole at the summit of Mount Shasta from a deep-seated reservoir of partly molten rock. Mount Shasta can release

Climbing

The summer climbing season runs from late April until October, although many attempts are made in the winter. In winter, Sargents Ridge and Casaval Ridge, to the east and west of Avalanche Gulch, respectively, become the most traveled routes, to avoid avalanche danger. Mount Shasta is also a popular destination for
backcountry skiing Backcountry skiing ( US), also called off-piste (Europe), alpine touring, or out-of-area, is skiing in the backcountry on unmarked or unpatrolled areas either inside or outside a ski resort's boundaries. This contrasts with alpine skiing, which i ...
. Many of the climbing routes can be descended by experienced skiers, and there are numerous lower-angled areas around the base of the mountain. The most popular route on Mount Shasta is Avalanche Gulch route, which begins at the Bunny Flat Trailhead and gains about of elevation in a round trip of approximately . The crux of this route is considered to be to climb from Lake Helen, at approximately , to the top of Red Banks. The Red Banks are the most technical portion of the climb, as they are usually full of snow and ice, are very steep, and top out at around before the route heads to Misery Hill. The Casaval Ridge route is a steeper, more technical route on the mountain's southwest ridge best climbed when there is a lot of snow pack. This route tops out to the left (north) of the Red Banks, directly west of Misery Hill. So the final sections involve a trudge up Misery Hill to the summit plateau, similar to the Avalanche Gulch route. No quota system currently exists for climbing Mount Shasta, and reservations are not required. However, climbers must obtain a summit pass and a wilderness permit to climb the mountain. Permits and passes are available at the ranger station in Mount Shasta and the ranger station in McCloud, or climbers can obtain self-issue permits and passes at any of the trailheads 24 hours a day. Climbing Mount Shasta can be done in one day; however, it is often completed in two days. Climbers can ascend from Avalanche Gulch and camp at either Horse Camp (elev. ) or Helen Lake (elev. ). Camping at a higher altitude also helps with acclimatization and often reduces the risk of altitude sickness.
