Snowpack

Snowpack Obsvervation #1 Comments: New snow bonding to old snow surface. Very minor cracking in isolated areas of drifted snow. New snow moist by noon, noticeable settling. Good freeze prior to snowfall, with 8 to 15 cm of P-K hard refrozen snow. Old snow is moist and unconsolidated to ground.

Snowpack Obsvervation #2 Comments: Small pockets of soft wind slabs in drifted areas. Pockets were not extensive, 1-3 m in width. Reactive and broke easily on a storm snow interface 20-30 cm deep.

Snowpack Obsvervation #3 Comments: New snow bonding to old snow surface. Very minor cracking in isolated areas of drifted snow. Old snow surface was 4F to P hard. Underneath, old snow still dry and faceted to ground above 11000 feet.

Avalanches

• Avalanche Description: Many small naturals ran overnight or early Tuesday morning. All above treeline on east and northeast aspects, starting just below ridge lines and cornices. Looked like they ran on storm interface, occasionally old snow surface. Shallow, but some propagated widely. Observed from Woods Creek north through Current Creek.
