Observation Narrative	Habitat is a frequently flood-scoured bedrock outcrop on a terrace above the Potomac River. Small, temporary pools of water are present within the rocks. Sparse, shrub and graminoid-dominated vegetation is rooted in crevices. Lichens, particularly Xanthoparmelia conspersa, dominate.
