Abstract

21 tree-ring stations, totaling 116 trees, were sampled at varius localities within the forest trimlines fronting the Agassiz and Jackson glaciers. It was found that both glaciers began to retreat from their maximum late-Neoglacial positions c1860. Retreat rates, derived from the tree-ring data, appear to have been modest (under 7m yr-1) until c1910 when they increased, reaching more than 40m-1 for the Agassiz Glacier between 1917 and 1926. Since the mid-1940s the retreat rate of both glaciers has slowed markedly.-from Authors
