Snow bikers saw the debris and crown of a large avalanche that broke on a heavily wind-loaded slope on Mt Jefferson in the Centennial Mountains. Look to the upper left of the photo to see what they estimated as a 6' deep crown. Photo: R. Gravatt

From obs 3/20/23: "Yesterday (3/19) we toured up into Emigrant gulch. At around 2pm we observed a small point release on the East face of Emigrant, either a small cornice break or wet loose, that ran for about 200ft before stepping down to a deep slab that appeared to be about 3ft deep and 100ft across."

As we returned to Frazier Basin from below, we saw five natural avalanches on the southeast-facing wall of the basin. They entrained only the 1 to 2 inches of snow that had fallen during the day. However, they were notable in that they ran 500 to 700 vertical feet. They indicate that the new snow may not bond well to the old snow surface. A crust formed by the recent warm temperatures and sunny skies is the subsurface that snow is falling on. This will become a more significant concern as more snow falls this week. Photo: GNFAC

"Attached are a few photos of old deep slab avalanches north of town... the south face of scotch bonnet. Hard to tell the depth of the crown but it’s very visible from the lulu road, so probably pretty deep." Photo: Z. Peterson
