No observed natural avalanche activity. Lots of loading in South, Central, and the Fan.
We performed a number of tests in a pit on a 26deg slope on a SE aspect, finding 60cm or so of upside down wind slab on a crust. A second crust, (perhaps two . . .
We encountered an up right slab varying from 10cm to 40cm it was well bonded to the old ice crust. Under the ice crust was a 2-4cm layer of 4F .5mm grains. They were dry, but easy stuck together to create a snow ball. Pole probing showed a pretty . . .
We climbed a long snow gully left of Dodges Drop in Tuckerman Ravine to the Boott Spur ridge, looking for wind slab formation out of curiosity as this slope has a similar aspect as Escape Hatch in Huntington Ravine, which avalanched naturally during . . .
Partway up Willey’s Slide, we saw a large shooting crack (approx. 50ft long) form where we were standing in the snow below an ice bulge, so we decided to bail. The snowpack was variable and included sections of firm scoured snow, sections of soft . . .
The 9.5″ of 17″ snow on 2/27/2020 with wind from the ESE then W produced a number of natural avalanches.
-Escape Hatch in Huntington Ravine. Large avalanche D3 cleared trees to within 15 feet of the Huntington Ravine Trail. Debris measured over 10 . . .
See snowpilot profile for snow structure. We observed cracking around our pit location, with clean interfaces 10-20cm deep, though all our test results (ECTP15 and ECTP21) failed on a sun crust (65cm down) we think formed sometime last weekend.
We . . .
We saw evidence of roller balls, and small wet loose avalanches from the previous days warm up (R.5 D.5) We encountered good snow conditions, however we did experience short sections of up to 10cm boot pen in the fan on the southernmost aspects in . . .
Found good snow above 4,000 feet.
Skinning up Hillman’s for a run Wednesday late afternoon encountered a firm and settled snowpack with 4+ inches of powder on top.
I observed a consolidated base and anticipate new snow on this surface/snowpack will . . .
While on descent from the Standard Route area at Frankenstein at 1:30pm, with a temperature of 40F we observed a debris pile from a wet loose/point release below some rocks near where the climbers trail begins to head down rib between the north slabs . . .
Our avalanche course visited the lower part of Gully #2 in GoS today to escape the crowds. While practicing compression tests, we found sudden planar fractures during our easy taps. These fractures were on a thin layer of small facets 20cm down, . . .
