It is unclear whether the Darling scarp is a rapidly evolving landform responding to recent tectonic and/or climatic forcing or a more slowly evolving landform. In order to quantify late Quaternary rates of erosion and scarp relief processes, the AA
. obtained measurements of the cosmic-ray produced nuclide beryllium-10 (10Be) from outcropping bedrock surfaces along the scarp summit and face, in valley floors, and at stream knickpoints. Results and discussion. Cosmogenic 10Be analysis provides a useful

in youthful karst where valley floors are narrow. Here, footcaves not only may have been initiated, but also occasionally maintained, enhanced, and modified by migrating streams, as well as by scarp-foot weathering and sapping. Microorganisms that colonize

in northern Pakistan. Regolith thickness was sampled at exposed bedrock outcrops along the river bed and scarps. At unexposed sites the regolith-bedrock interface was identified through electrical resistivity survey, thus providing an indirect measurement

by fluvial and glacial erosion and scarped head-valleys that represent the current knickzones. Quantitative data indicate that glaciers had a much higher erosional capability than fluvial activity in the higher sectors of the Main Cordillera. Comparison
