This avalanche was reported on Thursday and appears to be from a natural cornice fall. Heavy snowfall and persistent winds this winter has led to very large cornices along upper elevation ridge lines. The Park City ridgeline is an especially prominent area for cornice development. The slide was reported to be 400' wide with 10-15' of debris in places. It also snapped some large trees. The observer who noted this avalanche performed a beacon search of the debris field as they were unsure if it was human triggered.
