We were surprised when this medium sized slab pulled out on us in Red Creek Drainage in Weber Canyon. The first skier set the left track in this picture with no issues. I made the second track just to the skiers left and the slab remotely released and piled up in the small ravine at the bottom. The slab released on a mellow east facing slope at about 32-33 degrees, but the concave roll where the slab pulled out was slightly steeper. We didn’t get in to close to investigate but it appeared the slab released on a weak layer between the old crust and new snow received in the last week or two. The slab was about 75 feet wide and ran about 400 vertical.
