Description :
Dendrogeomorphology was used to investigate past events on a cone affected by both debris flows and snow avalanches. The AA. report on results of 520 cores from 251 trees sampled on the Birchbach cone (Swiss Alps), for a 252 yr period, extending from 1750 to 2002. Thereafter, the AA. assess the approximate area affected as well as the origin of past debris-flow and snow avalanche events on the cone using tree-ring records in conjunction with the results from geomorphic mapping.
