GMRE, Inc. geologists have been mapping the
bedrock geology of 7.5 minute quadrangles in
central Pennsylvania as part of the State Map
program. The geology in this part of the state
ranges from Cambrian carbonate rocks to
Devonian shales and siltstones.
The index map shows the current status of
quadrangle mapping. The Lewistown, Belleville,
Allensville, and Newton Hamilton quadrangles
have been mapped by Geologic Survey staff
geologists, while we have mapped the Burnham,
Barrville, and McAlevys Fort quadrangles.
Currently we are mapping the Julian and State
College quadrangles.
