At 4,800 feet, a small but apparent crevasse could be seen at the fork in the gulley. Roughly 12 feet long, the crevasse was obviously undermined and a significant amount of water could be heard flowing under the snow. About four feet above the . . .
Hard crust on top of loose snow, couldnt finished digging for an extended column without snow failing.
Crevasse running in the center fan below the Huntington Ravine Trail past the Harvard Bulge to The Diagonal Gully entrance. Currently very narrow. Clearly visible from Pinnacle Gully.
Approx 4400’ elevation.
Otherwise firm and breakable crust . . .
Beautiful bluebird day the wind had let down as the went on. I was guiding and we had just got back down to alpine garden after summit of Mt Washington when heard a scream from the party above us and 2 took a long sliding fall from just below split . . .

Photo submitted to view the extent of debris and path from the 20200227 D3 avalanche. We descend the Escape Hatch and witnessed 8″ diameter spruce krumholtz broken clean. Impressive.

Today (3/8) on our AIARE Level 1 course we dug pits on the climbers left side of the Right Gulley in Tuckerman Ravine at the 4,650 foot level. We found 30cm pencil hard snow on top of the crust layer. We had one CT 26 Q2/RP at this interface and had . . .
There were few signs of instability, crowds, or wind today in the lower reaches of Raymond Cataract. Large ice blocks had fallen thirty feet and impacted the 33-degree slope without triggering avalanches. The ice blocks appeared to have fallen days . . .
Similar location to earlier this week. Results show propagation on a 1cm later of facets between two ice crusts. The upper ice crust is becoming less evident and easier to break.
ECTP 22 down 50cm
Confirmed with a second ECT (same pit) showing the . . .
We preformed a number of compression tests, one extended column test and one propagation saw test on a small east facing hill, sheltered by trees, near the avalanche devastation below Hillman’s Highway. While the nature of the terrain may not . . .
