Rush Run Ravine is one of a series of ravines that drain into the Olentangy River in the City of Columbus. All of these ravines cut into the Ohio Shale, found in the Devonian bedrock exposed in a strip in the center of Ohio, running from Adams/Scioto counties in the south, up through the heavily populated counties along the shore of Lake Erie.

Sources describing minerals in the Ohio Shale in the northern part of the state can be applied to the Ohio Shale in general: it is a similar geology. Thus a similar pattern of mineralized concretions (containing ferroan dolomite, calcite, quartz, baryte, and aragonite), pyrite disks, and mineral efflorescences (alunogen, botryogen, copiapite, epsomite, gypsum, hexahydrite, melanterite, ferroan pickeringite, and rozenite) can be found in central Ohio exposures of the Ohio shale. In addition, chert nodules weathered out of limestone can be found in the stream beds.

Rush Run Ravine runs about 2 miles from near the Anheuser-Busch Brewery near I-270 and I-71, south to Morse Rd. then south-west to the Olentangy River. It is easily accessible through the undeveloped Rush Run Park (the lat/long below) or Walnut Grove Cemetery (off High Street).

Concretions are more difficult to find than in other area ravines due to the lack of much exposed shale, but broken material can be found in the streambed.

This is an urban site, and much of the property is private upstream from the Cemetery (and the Cemetery is also private, but accessible).
