More Cracks

CB Avalanche Center 2017-18 Observations

Location: Paradise Divide Area
Date of Observation: 12/30/2017
Name: Syd D

Subject: More Cracks
Aspect: East
Elevation: 11800

Avalanches:

None observed

Weather: Breezy with scattered clouds.
Snowpack: Toured up Poverty Gulch to an easterly face at about 11800′. As we were skinning up the last of the climb, a large crack set off, it was about 100 ft long and produced a loud “cosmic” sound. Unfortunately, I did not get a chance to see how deep it propagated. We did not experience any other cracking, collapses, or any other avalanche obs during our tour. After a investigatory pit we found that the total snow-pack is about 115cm. I did a small column test that produced a sudden collapse with moderate taps below the sun/dust crust as well as a shovel sheer test that failed with moderate pressure just above the sun/dust crust.
