Description

Devil's Racecourse in Ft. Ritchie, MD is a 700-meter-long blockfield created when the area experienced a periglacial climate during the Pleistocene. It is thought that boulders of Weverton quartzite from South Mountain on the west and Catoctin metabasalt from the east weathered out of their respective mountains and were gradually transported and deposited here by gelifluction. In non-dry periods, visitors to Devil's Racecourse can hear a stream running beneath the blockfield, and can even see it if they peer down the right holes.

View is to the south.
