Set off an slab avalanche up Farminton today about 3:30 pm. It was 100 feet across and 3 feet deep the pile at the end was five or six feet deep. I was side hilling on a North East slope about one bowl South of the towers. This was the kind of avalanche that could have killed you. I was side hilling toward the top of a 100 yard climb when I decided to cut into the hill harder and go over it. Right when I cut hard into the hill and just as I was starting to point fairly vertical the hill slid. I kept it pinned and barely cleared the gap from the sliding slab to the part of the hill that did not slide. It was actually pretty abrupt when I hit the wall of snow that did not slide with my track. It was what my insticts told me to do and it was the right decision this time. I showed the other riders back there what happened and we all got out of there.
