Wind Loading in Poverty Gulch Zone

CB Avalanche Center 2019-20 Observations

Location: Paradise Divide Area
Subject: Wind Loading in Poverty Gulch Zone
Aspect: South
Elevation: 10,000’

Avalanches: Multiple natural wind slab avalanches were releasing on south facing convex rollovers that had a crust. Wind slabs were releasing anywhere from 2 inches to 12 inches thick. Our party also triggered a wind slab while skinning uphill in low angle rolling terrain. These avalanches only ran up to 40 feet, not a lot of energy and not enough snow to bury a person, but enough to knock a person off their feet.

Weather: Very gusty winds, Moderate temperatures, cloudy skies becoming clear after noon.

Snowpack: South facing aspects had a crust, with active wind loading, creating slabs up to 1 foot thick by noon.
