Observation Narrative
The clifftop habitats contain some internal heterogeneity, but such conditions are typical on and around large rock outcrops. About a third of the plot area is situated on a steeply sloping area with relatively deep (but extremely stony) soils; another third is on a gently sloping rock outcrop surface with local organic mats; the final third consists of very steep rock faces and narrow ledges just below the lip of the cliff.
Plot location: Shenandoah NP. East flank of Big Devils Stairs, adjacent to the Big Devils Stairs Trail near the southern end of its passage across the top of massive greenstone cliffs (the trail cuts across the NE corner of the plot).
