This is <>:ie <>!' the deepest wells drilled in southern Somerset County of which the Survey 
has record. The well is on the axis of the Deer Park anticline, about midway between 
Great Savage and Meadow mountains. Apparently the first formation penetrated is the 
Jennings. This formation in Garrett County, Md., is 3,000 to 5,000 feet thick and is com- 
posed of shales, sandy shales, and sandstones. It contains beds corresponding in age tci 
the Chemung, Nunda, and Genesee epochs of the Devonian period. Below it is the Romney 
formation, also Devonian. 1.600 feel thick, of sandstone and shale. 
lit cord of well in Greenville Township, 1 mile north of Pocahontas.
