Mount Shasta

Today’s cold temperatures and wind will keep many snow surfaces near and above treeline hard and unforgiving. The primary hazards are uncontrollable falls and variable surface conditions. Bring a helmet and mountaineering tools if traveling on steep slopes or major alpine features. Protected, solar aspects near treeline offer the best chance for softening surfaces. 

Mount Shasta and the surrounding mountains hold a patchwork of snow conditions and surface types, most of which are hard and well consolidated. As a result, avalanche danger is low. Today’s colder temperatures and increased wind chill make variable surfaces and the risk of an uncontrollable fall in steep terrain the primary concerns. Carry traction tools—boot or ski crampons and an ice axe—to minimize your risk and maximize your safety. A helmet would be a wise choice too. 

While unlikely, small reactive wind drifts may persist in extreme alpine terrain. These drifts are expected to be isolated and small (D1 or less) and confined to steep and complex terrain features. Watch for blowing snow and assess drifted areas for signs of instability, such as shooting cracks or blocking.

Remain flexible with route plans and objectives if you observe unstable snow or encounter unexpected or undesirable conditions. Nearby weather may lower cloud ceilings, which would impact visibility in areas above treeline. Don’t ascend into a whiteout.

A trip to Lake Helen yesterday confirmed the widespread variability of surface conditions on the upper mountain. Find out more HERE.

The lack of precipitation for most of January has left skiing and riding conditions in need of a refresh. While winter recreation remains possible in most areas, expect a medley of wind-affected snow, wet snow, corn-like snow, dry snow, frozen ski and sled tracks, and icy surfaces. Shallowly buried and visible obstacles are abundant at lower elevations. Ski and ride with caution. Wind-sheltered slopes near and below treeline hold the smoothest surface conditions.

Climbing: As always, climbers should keep a close eye on the weather. A winter ascent of Mount Shasta is a very different undertaking compared to the friendlier conditions of spring. Key hazards include firm, icy surfaces that can create slide‑for‑life scenarios, rime icefall, rockfall, negative wind chills, and sudden loss of visibility. Never climb into a whiteout. Carry reliable navigation tools and know how to use them. A full mountaineering kit is essential: 12-point crampons (NOT microspikes), ice axe, and helmet, and the skills to use them proficiently.
