We came upon this avalanche heading down Logan Canyon (Hwy 89) around 4:30pm. Looked very fresh as the plows hadn't cleaned up the debris pile yet. It covered the northbound lane but cars managed to drive through/over.
This small avalanche is a bit surprising given the low elevation as well as west aspect. In this part of the canyon though the winds tend to swirl and load terrain features like gullies and cut-banks.
Had nowhere to safely park but the slab seemed to be primarily storm snow and slid on the old snow interface.
Also saw some blown-in, small slides by Red Banks, another low elevation but east facing area.
