Difficult Run Photo Journal
Difficult Run is a tributary of the Potomac River located near Great Falls, VA. The tributary channel is cut through very resistant late Pre-Cambrian age meta-sedimentary rocks. The stream periodically floods as it did in September, 2011 when Tropical Storm Lee moved through the area. Significant erosion resulted which the students captured in a photo journal during a field trip to the stream. The project included the incorporation of different types of data and field observations.
