Friends got back and while they were in Oasis they released a slab about 200' wide with about a 500' run. Base of runout was up to 8' deep. One guy climbed to the top and parked, when the second guy lined up it released and he turned out and to the side. The release did not occur until about 10 sec. after the first rider was done his pull. Not sure of slope angle but all have taken avy course and climb ONE AT A TIME. Could have had bad results with more than one on the hill and a deep runout. Largest release any of us have started. Be smart and play/park as safe as possible. Saw pictures on one camera but not clear, need to download and maybe see more. Depth of slab can be seen but not much more.
