Notes

In Lamar Valley:

Today in Chrystal Creek my group of 4 skiers triggered 3 cornices. 2 remotely triggered and one small one while skiing off of it. The slope below was not steep enough to slide far. ~75cm of snow where we dug our pit on a North slope at 26 degrees. One slab ~23cm off the ground didn’t cause any real problems. Another hard slab ~35cm-42cm sitting on facets broke at ECTP7, CTPV. Had more whumphs than we could count and cracks that shot 30+ meters. Snow depth varied greatly, some wind loading.
