Observation Narrative	Plot positioned on a large, flat granodiorite outcrop with numerous quartz veins perched above the Potomac River west of Black Pond. The vegetation here is quite sparse, with scattered dwarfed shrubs and herbs rooted in cracks and crevices. Several stepped ledges and shallow pools of water are present within the sampling area.
