Although Mill Creek in the Absaroka Range is out of our advisory area, this avalanche from Sunday, March 9 is impressive. If you ski in these areas you will be especially interested. This is a direct quote from an email: "We triggered this slide in the flats above the ridge from about 5 ft away from the slope in the center of the photo where the trees meet the horizon. The slide initiated on an ice crust below a hard wind slab. The crown was 3 ft deep then stepped down to facets above the rocky ground. The slab was cohesive enough to pull 3 to 4 ft into the flats where we were standing (luckily far enough back not to go with it). It propagated through all the gullies in the bowl North to East facing. I didn't dig a pit at the crown, but did on the same slope, same aspect near the toe of the debris about 800ft below the crown. Results ECT30. In fact, the column stayed together even after toppling it over. We weren't planning on skiing this face because there were numerous recent slides on all N to E facing slopes on all the mountains from Emigant to Knowles." Photo: K. Konz
