Morphometric data indicate 2 distinct erosion processes operate in these steep mountain valleys. The AA. determined the rates of these processes using cosmogenic beryllium-10 (10Be) in pooled soil and stream sediment samples. Denudation in deep, glacially scoured valleys is characterized by rapid, non-uniform processes, such as debris flows and rock falls. The denudation rate in each basin represents a binary mixture between the rapid, non-uniform processes, and soil creep. The AA. further show that the spatially averaged denudation rate is that of the local rock uplift value, even though a bedrock knickzone at the valley outlet hinders baselevel lowering and thereby disconnects the valley from the regional rock uplift trends
