Emplacement of hot volcanic debris onto a thick snowpack can trigger hazardous rapid flows of sediment (including ice grains) and water, which can travel far beyond the flanks of a volcano. Five papers in this volume document aspects of rapid-snowmelt events that occurred in Mount St. Helens between 1982 and 1984; one paper offers a theoretical explanation of features present at depositional contacts between hot rock and snow.
