From an email:
"I’d like to report an avalanche incident that occurred today, 3/6, around 2 PM on the NE face of Mt. Blackmore in the Hyalite Canyon area. On the approach, I dug a pit at 9400’ and found a very stable and deep snowpack, with a somewhat definite weakweak layerbetween high and medium density snow about 8” deep. The layer did not slide slideopagate in an extended column pit test, so my partner and I decided do ski the direct line from the summit. I skied first, making a ski cuski cutbelow the ridge line that did not result in any sloughing. I skied the line without mishap. My partner followed, traversing onto a shallow, steep pocket, releasing the avalanche. It propagated down and out in both directions, resulting in a v-shaped crown about 100’ across and 8-12” deep. The slide ran slidearound 9800’ to 9400’. My partner was not caught and was able to traverse out and ski down safely."
