Abstract

The AA. investigated the age of fill terraces and incision in a small Front Range catchment to add evidence to the discussion about processes that drove canyon cutting in the Front Range. In some places, fluvial deposits may have been eroded particularly between about 15 ka and the present. Incision rate estimates derived from terrace ages allow to explore the correlation between climatic events and the initiation of incision and to comment on the origin and persistence of convex-upward longitudinal profiles or knickpoints. This study provides an example of how modern geochronologic techniques allow to understand better rivers that drain glaciated catchments
