Weak snow formed in January is buried 2 to 3 feet deep below a hard slab. It is becoming less likely that you will impact these weak layers, but it is still possible on very steep northerly slopes. Pockets of buried surface hoar near the top of the drought facet layer are most concerning. The distribution of this buried surface hoar is spotty, but mostly between 8,000 and 9,500 feet on very steep (35°+), shady, and sheltered terrain. Identify terrain with these characteristics and evaluate carefully. Keep an eye out for very steep terrain traps around creek gullies that often harbor surface hoar.

This avalanche was triggered yesterday on a sheltered slope which had a skin and ski tracks on it.
