Colorado Avalanche Information Center

Pit dug in area where cross loading occurred. Localized cracking in areas where the top wind slab was < 15 cm thick.

Average crown height 60cm; Max 80cm, Min 30cm. Avalanche failed on a layer of 1mm FCsf immediately above a MFcr 89cm up from the ground. Avalanche propagated approximately 450 feet wide and ran approximately 350 vertical feet. Slope angle increased from 30 degrees at the crown to 36 degrees as the slope rolled over. Debris was measured up to 320cm deep.

Pit dug on slope representative of 80 highway path. Some DH present at bottom of pit around rocks. Possibly a thin layer of FC at 87cm interface, however hard to isolate on card.

Winds increased through the day
