Natural new snow slide on steep due north aspect in grizzly gulch. High PI and wind around 3pm is the likely culprit. I did a quick beacon search to make sure no one was buried. When I went up the debris, it turned out the slide was larger than I though. About 200' wide and 150' vertical hitting the main skin track up grizz. It was only about 6" deep bit d2 r2. Additionally I saw a few more crowns up the ridge in the open steep north facing slopes. Seems like there was a natural cycle during the high PI and winds at 3pm.
