Tree-Ring Dating of Snow Avalanches in Glacier National Park, Montana, USA

Abstract

Snow avalanches are major hazards to humans occupying or visiting mountain ranges around the world. Accurate dating of past high-magnitude snow avalanches is important for a better understanding of their frequency, extent, and climatic driving factors. As climates change, prediction of shifts in avalanche frequency and/or magnitude are better enabled when a thorough understanding of past avalanche occurrences exists.
