My riding partner triggered a wind slab on the NE face of Little Superior heading into Cardiac Bowl. He punched a ski cut style line on his snowboard to test the stability because the wind pockets looked a little sketchy, and it ripped out from underneath him about two feet deep, and ran pretty much full-course to the bottom of the bowl. It propagated up about 50 feet from the initial break near the ridge line, and was about 50 feet at its widest point. No injuries occurred, and my riding partner didn't even go for a ride, because he was able to seek safety on the ridge.
