Observation Narrative	Plot is located on a low silty bar at the foot of an outcrop/ boulder complex on the shore of the Potomac River in Mather Gorge. A permanent seep flows through habitat, which is wetter than most similar habitats in the Gorge. Herbaceous annuals dominate the rather sparse vascular plant cover.
