Avalanche Location:
Observed from Hwy 2 on Feb 7 around sunset and suspect it ran sometime in the previous 24 hours. Visibility was limited then and same for today, so details about the slide are rough estimates. Could not see the runout and the debris terminus. I suspect the buried surface hoar as the failing weak layer.
