Observation Narrative	Sparsely vegetated outcrop on bedrock terrace along, and approximately 14 m in elevation above, the Potomac River. Habitat is periodically scoured by large floods (return interval ~ 7 to 12 years). Small pools are present as microhabitat inclusions within the generally very xeric habitat. Xanthoparmelia cf. conspersa is the dominant lichen.
