From email: "We were sledding and I was riding up below the steeper part of the hill and set this off above me. I was able to ride out untouched. We estimated it was 200 feet wide and 50 feet tall and a foot deep at the crown. Because of the small gully that was there before it slid it would’ve easily buried someone. We guessed there was at least 5 feet of snow burying the gully or low spot next to the hill."
