Erosion of Shenandoah National Park



Shenandoah National Park is a steep, forested refuge not far south of our nation's capital. The Park is long and narrow, defined by a bedrock ridge that contains several distinct lithologies. In collaboration with the USGS, we collected fluvial sediment and bedrock samples from the park and determined that most lithologies are eroding at similar rates, except quartzite which is eroding more slowly than the others. Rates of erosion are low, on the order of 10 meters per million years.
