This is a boulder on display at Jennings Randolph Lake in Mineral County, West Virginia. There have been numerous theories and speculations as to its origin, ranging from a pictograph made by prehistoric man, an indian carving, the impression of the skin pattern of a giant lizard, or evidence of a visit to earth by an early travelers from outer space.
After examination of the phenomenon, Corps of Engineers geologists and those of other agencies have concluded that it is a natural geological formation. Although such formations are not common, similar patterned boulders were found on the east side of Tea Creek Mountain in Pocahontas County, West Virginia. Dr. Jack B. Epstein of the Geological Survey, U.S. Department of the interior, explained that the waffle rock is part of the Conemaugh geologic series that was deposited about 300 million years ago during the Pennsylvanian period. It is surmised that the waffle rock is a large loose boulder that fell from a parent outcrop somewhere higher up the slope, many decades ago, before the present trees grew.
