Location

• BC Zone: Gunnison
• Route Description: Zone: Northwest Mountains Route Description: Anthracites

Weather

• Weather Description: Sunny skies and reasonable temperatures above the inversion. Light winds at ridge top.

Snowpack

• Snowpack Description: I looked for buried surface hoar in several spots on north and northeast aspects and didn’t find it. Traveled through a northerly near treeline feature that often forms Wind Slabs and found only soft storm snow. No cracking in storm snow or signs of instability in terrain with snow depths well over 2 meters. Southerly slopes below and near treeline became moist by the afternoon.

Snowpack Obsvervation Cracking: None Collapsing: None

Avalanches

• Avalanche Description: An unreported avalanche below treeline on a northeast-facing slope from near the middle portion of the Anthracites skin track. Did not inspect the crown, but it hammered the typical skin track breaking at least one tree, 5 inches in diameter, and toppling several others over. Crown looked around 4 – 5 feet thick. I suspect it ran towards the end of holiday storms around 12/30. This is the second time this winter that the Anthracite skin track has been impacted by a natural avalanche. Small natural Wind Slab from 1/8 beneath a cornice in East Bowl.

Date: 2021/12/30 (Estimated) Observer: Eric Murrow Organization: CBAC Area Description: North side of Anthracites. Overran typical up track. Landmark: Anthracites Comments: Could have been D3 due to impact pressures, but best guess puts debris volume less than D3. I suspect more trees were mowed, but buried.
