This is in an area called "Review" in the Black Iron Bowl in the Telluride Ski Resort. To get to the Black Iron bowl its about a 20 to 25 min hike up a ridge to get to 12,250 ft. The recent warm weather has made the snowpack very weak and we had just gotten about 5 inches back there on top of a weak layer in the snowpack. I was skiing inbounds even though its more like side country skiing, so I didn't think anything would slide. I made a hard stop after some nice powder skiing and I triggered the whole snowpack. As you can see in the video, the area in which I came from was down to the bedrock and there was no snow left. I would call it a D1 Avalanche. I got lucky it carried me where it did and not over the cliffs.
