Partial burial at anthracites

CB Avalanche Center 2019-20 Observations

Location: Kebler Pass Area
Date of Observation: 12/01/2019
Name: Lee pow

Subject: Partial burial at anthracites
Aspect: North, North East, North West
Elevation:

Avalanches:

Big chute on anthracites. Dropped 3 cornices on big chute from the overhead cornices skiers left at top of run. Most of the gut of the run slid below the first tree band/rollover, 100cm to ground. Proceeded down the run and stopped at first safe zone on skiers right, when I peeled back onto the run, some hangfire caught me and carried me 100 feet, buried to neck. Self rescue.

Dug an ect at the bottom of the run before dropping (thought a lower pit would be more indicative of the line vs digging above)
Lots of spatial variability

Talking to others at the sleds, many cracks were observed everywhere at the cites, but 7th bowl, due to buried weak layer. One crack was reported to move ~4 feet but did not run.

Weather: Clear and cold
Snowpack: About 100cm
