A rhomboid plaquette from Arkfeld Site

Arkfeld Site, #44FK731, 'Rhomboid plaquette'
Clear Brook, Virginia

Adam Arkfeld has identified a recurring pattern of these diamond-shaped stones which have been sculpted using a "bend-break" or "buffer technique" to make the relatively straight sides. They have been found at several portable rock art sites and likely had some kind of symbolic significance to their Stone Age makers.
