Parfrey's Glen Trail In Gorge - NAT09 VAC09 - 86
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.
The uppermost part of the Glen, with its jumble of huge fallen rocks, has a depth of nearly 100 feet. ( "Devil's Lake State Park Visitor", Wi DNR PUB-PR-111 2009).
