Avalanche: Summit

Location: Fresno

Route & General Observations

Got out in Summit Pass today looking for recent avalanches, how high it rained, and how the snowpack was adjusting to over 10 days of warm weather and strong winds. We saw a new glide avalanche on Gilpatrick Mtn and several small avalanches. The rain crust disappeared around 2400.’ There was a trace of new snow on top of the rain crust and the rain crust was supportable. At higher elevations we could see how the wind did a great job scouring ridges and gullies and loading leeward slopes. We did not get concerning results in our pit, however, at higher elevations the snowpack is probably quite different.

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

Patches of blue in the sky in the morning, transitioning to overcast clouds and snow in the afternoon. Light winds out of the east that were slowly getting stronger.

Snow surface

Supportable crust several inches thick which gradually got thinner as we skinned higher. Trace to no snow on top of the crust. At 2400' the crust disappeared, and the skiing was pretty good. Higher elevations had significant cross loading from east to northeast winds and wind ripples on faces exposed to the wind.


Closer to the road the snow below the rain crust was moist. We dug 2 pits at 2300' on an east aspect, 25 degree slope. We found the snowpack to be right side up with a depth of 95cm and our test did not produce concerning results (CTN, CT27 down 35cm below TG crust, ECTX). There was a 0.5" crust layer just below the surface. The thanksgiving crust was still visible about a foot from the ground with a layer if ice at the ground.
