This report is from Monday the 4th not the 3rd but application will not allow me to use correct d/t Saw evidence of an avalanche that ran down grizzly slide path during the most recent natural slide path. Size was hard to conclude as visibility did not allow us to see the start zone. Did 2 laps of different hospital gulleys with great snow and didn’t see a single soul other than our party of 3.
