SnowRock

In 2012, a 75,000 m³ rockfall onto snow-covered talus generated a distinct type of rapid, long-runout massflow of pure avalanche snow carrying the rockfall-produced scree piggyback. In the same area, fossil rock avalanche deposits show features similar to the 2012 event. The characteristics of 'two-layer' snow/scree avalanche transport, and its implications for hazard assessment and landform interpretation are discussed.
