I was above Mirror Lake when that happened but on a steep incline and could only see the dust flying off the mountain and not the landslide itself. I could see a group watching it up ahead of me where they had a clear line of vision. And obviously I could hear the incredible noise.

Spoke to a couple who ducked for cover a couple minutes later as they were coming down and they said it was a bit scary, as you might imagine. They were starting to take pictures and then realized they had to think safety first and ducked behind a big rock with a few others. They wouldn't have been hit, but they didn't know that as it was heading for them.
