Observation Narrative	Plot location: Steep slope along the Potomac River, north of the Fairfax Ruins; the plot is N-facing along a ravine perpindicular to the Potomac. See plot form for sketch of plot. This plot was difficult to navigate due to its steepness. Several trees in the plot are leaning significantly due to erosion of the slope. The leaf litter is thick against the tree trunks and fallen wood, but totally washed away in sections to expose mineral soil.
