Snowpack: Creamed corn up high to slush down low, south facing blue peak. Pica bowl, slush and wet slide debris

Avalanches: On the way up Highway 20 yesterday observed a large slab with a crown estimated to be 6 to 8 feet located in the upper Northwesterly facing Bowl off of the West Rib of SilverStar (near high point on skiers ridge line approx 6700 feet)It appears that in places it went to the ground and on the layer immediately above the ground. This appears to be recent. The slab broke 100 Vert feet or so below the ridge line. In the early Winters Creek headwaters. Hairpin, the rock walls above the three NE bowls south of Spire Gulch all went big recently, and ran to the valley, almost to their historical path boundaries. These large Avalanches deposited wet debris estimated to be 20 feet deep in places, in the Cave Bowl run out, with large chunks. Well worth a look. From Spire Gully southeast up the hairpin, these NE bowls are known as Cave Bowl, Cliff Bowl and Steroid Bowl. The next bowl to the Southeast is known as Pika Bowl below Pika Peak ( not to be confused with "Poster Peak", which really doesn't exist). Pika Bowl also had some debris that came off the walls, however the walls in that area aren't as extensive as the three other bowls so therefore not as much debris that only ran 300 to 400 feet or so. The Avalanche that came off the Cave Bowl walls entrained the snow in Lower Rock waterfall face down to bare rock.
