- 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.
This was shot on a foggy December morning. During the half hour or so it took to shoot, the fog burned off and the sun came out.
View is to the north.
