Quick report

Cracking
isolated

Lots of wind lead me to stick to smaller, less exposed areas today on the pow surf and snowmobile. I went to a mostly east, slightly north, facing bowl at the top of mammoth knolls, near the seismograph. I immediately noticed signs of wind loaded at the top of the bowl as winds had pick up considerably at 2pm. Elevation was about 8600ft. I observed the cornice from the top and gave myself lots of distance to ride around and looked at the area from a more north facing aspect. I saw it was a relatively small cornice and decided to drop on the more northern facing slope. On my second drop I moved more towards the cornice, still trying to give my self enough margin for error. That is when it broke, from the corner of my line ( see pictures). Slide did not run far, was made of all new wind loaded snow.

Avalanche

Triggered an isolated windslab event on an ENE face that propagated roughly 30 yards at 2pm on 02/14/24. Nobody was caught, crown varied from 40-55cm in height. Slab did not run far, only about 20-25 ft. Snow depth in that area was about 95cm from ground to top of crown. A few small growth trees were exposed after slide was triggered.
