Description :
Detailed measurements of sediment fluxes in the Northern California Coast ranges at Caspar Creek and Redwood Creek have provided estimates of physical erosion rates since 1963 and 1971, respectively. They used cosmogenic Be 10 to measure millennial-scale denudation rates averaged over 1400-8700 years at 6 catchments in Caspar Creek and 4 catchments in Redwood Creek. These measurements suggest that denudation rates at Caspar Creek are slower than rock uplift rates, implying that Caspar Creek is not in topographic steady state.
