We Saw this large natural avalanche off of gobblers knob back into alexander basin. The slide seemed to be triggered from a cornice fall above to upper pocket of the slide and then sympatheicly released the lower larger portion of the slide which had a crown of around 5-6 feet. I was able to dig a pit while on belay above the upper pocket of the slide. It seemed that the weak layer was buried depth hoar and large facets <3mm. There was alot of grauple in the area from the past storms and in my pit I also found a buried layer of grauple about 40cm below the surface and two thin rain/rime crusts one about 60cm below and the other about 100cm below the surface.

After we were done looking at the slide in alexander we headed over toward the main run off of gobblers. I had to boot of the ridge and I was walking in the skin track that another person had just made 15 minutes earlier and it was about 15-20 feet away from the edge when the cornice broke right under my feet. I dropped about 8 feet straight down instantly and landed on my feet. The Huge cornice went down the slope and iniated a good size avalanche consisting of mostly new snow.

I feel like everyone can learn from my mistake and remeber that cornices can break WAY further back much than expected.
