Hilton Creek Wind Slab on Facets and Impressive Nevahbe Debris

Observations

Skinned from 7,000' to 9,000' on N and NE aspects today. Temp at car was 0 degrees at 0930 but it felt like a warm spring day in the sun. Skiing ranged from poor to quite poor primarily on a scary breakable crust which had a thin layer of moist facets on top. Nonetheless, it was an absolutely gorgeous blue sky day without a breath of wind.

On a NE aspect around 8,500' with no tree cover I found a pencil hard 6" wind slab sitting on a FC-MFcr-FC sandwich. The top facet layer of the sandwich was very thin. The overlying wind slab sheared Q1 on the sandwich. The MF crust of the sandwich itself also sheared Q1 on the facets beneath it. The cold clear nights are still doing their thing.

I know there have been previous obs for the massive series of avalanches that came off the Nevahbe ridge last week, but I don't believe anyone has posted images of the debris. The debris and distance that it traveled is breathtaking. It went well down into the flats towards the Crowley Lake Campground.

Signs of Unstable Snow
