Brief description - Two wet avalanches, D2 in size, on the east bowl of Alta Diablo were observed. One was covering up recent tracks, start was unknown. The second was triggered by a ski track that cut across the east face on 32 degree slope. They both looked like they had occurred the day before.

Comment - The 3/9 report seems pretty accurate for danger zones and what we witnessed. However, on true north faces and areas shaded by trees, good and consolidated snow remains down to 8400’. There was rideable coverage on the south fork trail to the fire road crossing.
