Avalanches do some tremendous damage. Last summer I took our church's scout troop on a llama pack trip to a high mtn lake. I'd been there 2 years before and there was a beautiful meadow behind the lake with a good spring for water. It was a great place to camp with good feed for the llamas. Then we got hammered with a rough winter, over 200% normal snowfall. Now the meadow is covered with deadfall and you can't even get to the spring.
