Comments Named as a formation for Parker Bog Ponds, southwest part of Pierce Pond quad, northern Somerset Co., western ME. Type section is at Parker Bog Ponds. Occurs in a narrow belt 8 mi long. Consists of interbedded light-gray limestone and white-weathering, flinty, fossiliferous felsite (tuff) in beds a few inches to a few feet thick. Thickness is about 200 ft. Conformably overlies undifferentiated Silurian and Devonian strata suggested by parallel bedding; actual contacts not observed. Report includes geologic map and correlation chart. (ME003) Unit description from USGS GEOLEX website (ME078). GS - Greenschist facies; Protolith N - Limestone and/or dolostone.
