Route & General Observations

Toured to the top of Hatch Peak to investigate ski quality and to see how reactive buried persistent weak layers might be.

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

Two small collapses on old windslabs. Winds began to increase around 1:30pm with wind transport beginning to occur.

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

Fishhook parking lot @ 10:00am: 0 Fahrenheit, calm winds, and no precipitation, clear sky.
3800' Thousand dollar run @ 11:00am: 5 Fahrenheit, light winds, no precipitation, clear sky.
4500' Hatch Peak @ 1:00pm: 6 Fahrenheit, NE winds light to moderate, no precipitation, clear sky.

Snow surface

Snow surface was a mixed bag. Low density powder, crusts, and winds slabs were found. Leeward features held low density snow with some wind effect. New winds slabs 2" thick could be found in some areas, but were only 4F in hardness. Near ridge tops what appeared to be a thin rime crust could be found in some areas. Sasturigi and wind erosion could be found near ridge tops. From the summit of hatch peak most slopes appeared to be cross loaded.

Snowpack

Overall the snowpack seems to have poor structure, moderate strength, and low propagation potential. Two sets of ECTS were performed with no propagation. On the second round of tests some snow from the slab was removed to see if any propagation would occur.
