Observer Comments

Possible skier triggered D1 avalanche from today on SW aspect of Gold Cord Peak at 5250'. Hard to tell from our perspective if it was loose dry or a soft slab. Spoke to skier, skier mentioned debris below NE aspect of Gold Cord Peak, but they were unable to see a crown. Skier mentioned a noticeable slab at upper elevations on SW aspect of Gold Cord Peak.

Easy to initiate small loose dry avalanches on steep test slopes.
