Photo by Luke Koerten who wrote, "Saw this right accross the street from my house. Northwest aspect, thick windslab. Steep slope by Pete's hill standards, maybe 35-40 degrees." Notice the grass poking out of the shallow (1 footish deep) snow in the foreground, yet just a few feet away the depth is 2-3 feet deep of hard slab, wind drifted snow. These conditions are similar to what's up Hyalite in the tight gullies that avalanched and killed an ice climber on Friday.
