Where Interstate 64 crosses the Blue Ridge, there are terrific outcrops of Catoctin Formation greenstone. For another perspective on the same location, check out this GigaPan: http://gigapan.com/gigapans/126939 To see a piece of the Catoctin greenstone from this site in "macro" GigaPan view, click here: http://gigapan.com/gigapans/149431

The Catoctin Formation is dominated by a series of Neoproterozoic basaltic lava flows that were later metamorphosed to greenstone during the late Paleozoic Alleghanian Orogeny. This sample was collected at Rockfish Gap, to be imaged in conjunction with these two outcrop scale GigaPans: http://gigapan.com/gigapans/126939 http://gigapan.com/gigapans/126934 The hand sample is imaged perpendicular to the plane of foliation.
