Accident Report
Flattop Mountain, Rocky Mountain National Park - CO
Accident Summary
Skied DT today. Originally felt ok about the choice because much of it had slid yesterday. The snow from overnight was about a foot or less deep on a crust, low in the couloir.
Higher in the couloir the snow got deeper and my hackles went up, but hand pit results were not very planar and generally hard, but they were breaking consistently in the same place. We continued on. In the climbers left choke at the top we were fully wallowing, but again it felt rightside up and we continued.
Skiing down I triggered the slide about halfway down the upper crux choke. It broke just above me and swept me off my feet. I was luckily able to dig an edge in and arrest my slide fairly quickly.
The last couple of days have produced some of the most widespread avalanche activity I've seen in the park in my short tenure here. Sharing this story, which I feel quite embarrassed about, as a cautionary tale as we head into a bluebird weekend with lots of fresh snow.
Some avy stats. Aspect: SE. Elevation: ATL. Size: D1? (The debris was pretty shallow). Crown width: 8ish feet in the choke, propagated to about 30 feet wide below. Crown height: varied from 3 inches to a foot at its deepest.
This event is a near repeat from a day prior:
