One ski patrol yesterday reported a surprising avalanche intentionally triggered that was 3 feet deep and 300 feet wide failing on a density change above a melt freeze crust on an ENE facing slope at 8900 ft. When ski patrollers who work in the same terrain every day get surprised, we should take note before heading into backcountry terrain.
