Observation Narrative	The habitat of this plot is a long, convex, depositional boulder/cobble bar along the Potomac River in Mather Gorge. It supports a woodland of stunted, damaged, flood-trained trees, largely of Platanus occidentalis. Surface substrate consists of hard-packed sandy soils among prevalent water-worn boulders and cobbles, producing a difficult and periodically droughty edaphic environment for herbaceous plants.
