"We noticed this broken slab debris en route to ski the ramp north of Bridger Bowl yesterday. It was at the ridge line, and the crown was about 18 inches tall. It didn't slide very far, due to its lower angle (<30 degrees) and it is unclear if it slid naturally or from a skier poking over to check it out. It was located above cliffy, high consequence terrain."
