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, . . .
Bright sunshine, low wind. 35F tucked in sunny corner of the ravine. South facing aspects receiving the most direct sun warmed (moist snow) to about 10 cm down from surface. North facing aspects remained cold, dry.
Snow on the west side around ammonoosuc ravine was variable with lots of ice and rocks. West facing terrain was generally scoured except for pockets more sheltered from winds such as Monroe Brooke. Sasturgi all around the Lakes of the Clouds area.
We observed the following signs of natural avalanche activity, likely occurring this past Tuesday into Wednesday:
+Crown high in Dodge’s Drop with debris that ran into the dogleg of Hillman’s Highway
+Crown high in Left Gully
+Crown to looker’s right . . .
Overall, not much of a developed snowpack in Burt or Ammonoosuc Ravines, limited to small pockets of snow and lots of rocks. Did not see into Monroe Brook. From a distance, the small snowfields looked wind textured.
Recent snow last Tuesday-Wednesday has increased the depth of the snowpack in Crawford Notch, most notable on Cinema Gully on Mt Willard, Central Slab and Landslide on Mt Webster.
Debris from previous storm and wind cycle visible in the approach slope.
Repeatable, moderate hand shears with results 60cm down on pitch one in the pocket before the ice bulge. The shears are failing on an ice crust at approx 60cm. Otherwise there . . .
I observed significant avalanche debris on the floor of Tuckerman. This probably occurred Tuesday/Wednesday. The only visible crown was high in Left Gully. Considering the amount of debris, I would guess the Headwall avalanched during the cycle and . . .
The recent snow overnight did not allow for us to continue into the bowl as we saw the snow cracking on the trail up.
General comment: Swirling winds, snowing and wind blown snow. I had thought to dig a pit partway up #1. When my edge cracked a wind-buffed section just 40 yards from the upper cache, I turned tail immediately. On the way in, just above 3800′, on a . . .
