Snowmobilers and skiers can trigger slabs 1-3 feet in depth on a variety of aspects in steep terrain today. The potential for remote triggering exists. Because of this it is necessary to not only avoid steep terrain, but be alert to the possibility of triggering an avalanche from far away. Avalanches have the potential to propagate across large spans, including entire slopes. This was illustrated within the last day on Barber’s Point, where a natural avalanche released across the entire slope. Typical safe zones should be reconsidered when traveling below steep terrain. This includes terrain traps such as steep cutbanks and gullies. Give yourself a wide margin today to allow for surprises. These are unusual conditions and warrant respect. As temperatures rise during the day, expect avalanche potential to go up as well.
