Parfrey's Glen Trail Fern - NAT09 VAC09 - 1

This is quartzite conglomerate, a "plum pudding" stone, in which the quartzite "plums" are cemented in sandstone "pudding". The later represents an ancient sandy beach. The walls are zoned: layers of conglomerate alternate with bands where are relatively few pieces of quartzite. ( "Devil's Lake State Park Visitor", Wi DNR PUB-PR-111 2009).
