Located approximately 5.2 miles west of Petersburg on the east side of Powers Hollow Road, Grant County | 39.00339500, -79.22036500 | 455 | Exposed rock cliff edges. | Wild material | Heuchera alba is a narrow Appalachian endemic and globally imperiled (G2) taxon recorded only from West Virginia and Virginia that occurs in sympatry with H. pubescens and H. americana. According to Scheutte et al. 2018, the range for H. alba is restricted to high elevation acidic sandstone ridges and outcrops in the Ridge-and-Valley province of West Virginia and Virginia. In cultivation (central Iowa) the leaves emerge with subtle variegation that is lost by early summer. Flowers are creamy white to pale green. | 2096627 | OPGC 7572 |

The sites range from nearly xeric to dry mesic, at least on the surface. Plants are generally growing 4-10 m above the normal flow of the river; however, the Holtwood Dam is less than 1 kilometer upstream and debris found trapped in the boulders indicates that there is periodic flooding, at least, in the lower zone of 4+ meters or so above normal river flow. This habitat has a diverse assemblage of deciduous trees and shrubs as well as abundant herbaceous taxa. Slope: 0 to 60 percent. Aspect: Northeast (generally). Geology: The underlying geology of this area is probably of lower Paleozoic age and characterized as the Octoraro Formation. It includes albite-chlorite schist, phyllite, some hornblende gneiss, and granitized members. Soils: The area where this species occurs is right on the edge of two soil zones that transition from the river’s edge to mesic conditions upslope. The first is generally referred to as Rock Outcrop. This terrestrial matrix in which plants grow is largely exposed underlying rock geology with accumulated outwash, rock decomposition, and organic debris buildup. The second is Mt. Airy (80%) and Manor (20%) Series soils, 25 to 60 percent slopes, extremely stony (MRF). (Source: California Soil Resource Lab/NRCS Official Soil Series Descriptions).
