We were up at the lake and on the massive wall there was an avalanche. It was sooo loud and lasted about 2 minutes. We didn't see it because the visibility was so low. Then a few minutes later another one happened on the same wall. Kinda to the right, and we could see this one coming down as it reached the lake. My friend and I have never taken avalanche safety courses but it kinda seemed safe, they werent near us and didn't seem like an avalanche would happen near us either, there were no walls above us on our side. Pretty cool though
