Basalt stone eroded from surrounding ridge found on and re-inlayed onto Playa floor

30’x30’, temporary on-site construction.


Black Rock Diamond is a temporary on-site construction created on the ephemeral floor of a Great Basin Playa in eastern Oregon. Basalt stone found scattered on the Playa floor originates from the volcanic ridges that surround the enclosed lake.  Stones were collected from the dry lake floor, sorted by size and inlayed back into the Playa floor in a progression of gradated size within 30×30’ diamond shape. 

The elements of stone and lake; impending wind storms, rain or snow all interact and shift in a give and take of time.
