Mount Shasta

Normal caution is advised. Monitor steep solar aspects for any signs of wet snow instability as the day progresses and carefully evaluate old wind drifts in Mount Shasta's highest terrain. Climbers should be prepared for variable surfaces and overhead hazard, especially rime fall.

While avalanche activity is unlikely, it is not impossible. With warm daytime temperatures and a continued lack of subfreezing temperatures overnight, the upper snowpack may lose cohesion due to melt in certain areas. Stay alert for signs of instability like natural or triggered rollerballs and pinwheels, which may precede wet loose avalanches. If the problem develops, it will most commonly exist on very steep solar aspects, especially near rocky outcrops. Consider moving to a shadier aspect if needed. In extreme terrain, small avalanches could be consequential. 

Any remaining pockets of wind slab amongst Mount Shasta's most alpine terrain are probably small and becoming increasingly difficult to trigger. If travelling in these areas, assess for cracking in lens-shaped, wind-textured snow. Be prepared to adjust plans if needed.

For any climbers, despite sunny weather, winter conditions are still the norm and significantly increase the level of risk. Without adequate preparation, seemingly minor incidents can become major ones. Many high elevation terrain features, including the West Face, Casaval Ridge, the Trinity Chutes, Red Banks, Green Butte Ridge, and Sargents Ridge are coated in thick, hard ice that could shed at any time. Minimize your exposure beneath them. A full mountaineering kit is advised: 12-point crampons (NOT microspikes), ice axe, and helmet, and the skills to use them proficiently. A $25 Summit Pass is available at the Mount Shasta Ranger Station or for purchase by cash or card at Bunny Flat.

Surfaces throughout the forecast zone are highly variable, comprised of a hazardous patchwork of crusts and wind-affected, wet, sticky or soft, dry snow in isolated areas. Mount Shasta holds the deepest snowpack with shallower depths in the Eddy Mountains and Castle Lake area. Bunny Flat remains the best access for winter recreation and climbing. Check out our observations page for more details on recent conditions from around the forecast zone.
