Natasha Grim and I were on a day trip up to Mildred Lake from Convict Lake on Sunday, February 9. Just before 12:30 pm and two miles up from the trailhead, we heard a crash above us and saw heavy and snowfall come down what looked like the Mendenhall Couloir. We had plenty of time to get to a safe zone out of the avalanche path. The avalanche traveled at least 1,250 feet and ended near the top of the avalanche debris field at the base of Laurel Mountain. The avalanche forecast was low but there was a a bit of dust on crust from recent snowfall and high wind at higher elevation that may have loosen up the snow/rocks.

-Last photo added on 2/11 thru binoculars.  Best guess is that this was rock fall blown loose by the high winds resulting in a point release.
