Observation: Hatcher Pass

Location: Independence Mine area

Route & General Observations

Hardest part of the day was driving to and from HP with the honking Matanuska winds gusting 40-50 mph or more in the valley.
Toured from upper IM lot to look for potential new avy activity from an increase in wind this week. Scouring and sculpting abound, but no evidence found of recent slab activity.
Marmot and Microdot look skied out like the ski area. Ready for a re-boot!

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Observer Comments

No whumping, cracking, or collapsing . No new slab avalanches. A few small dry loose avys observed on SE and E aspects near Martin Mine around 3900', likely 3/14.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Winds gusted E/ENE to 22 mph on Monday , and 28 mph Tuesday- transporting some snow into new thin wind slabs on leeward aspects. Although winds have been constant in the valley- HP has not received quite enough wind for another natural cycle- at least not yet.
Recent cold weather and diurnal cycle still driving significant faceting out/drying out surface snow.

No new snow this week.

Temps have remained cold Mon-Wed.
-4.1 deg. F at 8am
-1 deg. F at 1200
2 deg. F at 1400

Snow surface

Variable. Recrystallized powder, wind board, old windslab, new windslab, sastrugi, wind waves. Some powder pockets in super protected locations consisting of facet powder!


Poor structure. Low energy. Stubborn slabs, but still possible to propagate persistent slab.
Some mid pack slabs are faceting out, and poor structure is all that is left.
