content: Shriver Chert is also known as Bedford, Bedford County, Bedford County Black, Eliberry, Mahantango, Old Port, Penns Creek, or Troxelville. It is black (N2), black with dark brown (7.5YR 3/2) shading along exterior edges that may be oxide film, white, or dark gray to black. Black (N2) & brown (7.5YR 3/2) varieties become very dark gray (N3) & dark brown (7.5YR 4/2) when heated at 450 degrees C. When weathered it becomes a yellow-gray that is described in West Virginia as "cherty siltstone". May have spiriferid brachiopod inclusions. Dull luster and medium texture. Translucent to opaque. Deposits include beds and lenses of deeply weathered chert, sandstone, and conglomerate.
