Park Guides

Description: Below is a list of park guides (“Trail of Geology”) published by the Pennsylvania Geological Survey. This series consists of nontechnical booklets and pamphlets for selected Pennsylvania state parks. The reports describe geologic features found in the parks; most of the guides include a geologic map of the park area. More detailed bibliographic information for each park guide is given in the Survey’s list of publications.

Disclaimer: Each user is responsible for the appropriate application of Pennsylvania Geological Survey reports and data as explained in our official disclaimer.

Related Publications: Several other “trail guides” outside of the park guide series are available through the bureau’s website:


Availability: All of the titles in the list below are active links that will take you to print-friendly PDFs of the park guides. Many of the park guides were printed on colored, oversized sheets of paper that were folded into pamphlets. The print-friendly versions were prepared on white, letter-size pages and  park-contact and bureau-organization information were updated.

Several of the original park guide pamphlets and booklets are still in print and may be ordered from the Bureau of Topographic and Geologic Survey. The titles of in-print park guides are followed by a link to ordering instructions, where you should follow the instructions for free publications.

The published printed copies of park guides can be borrowed from the Survey library or possibly from one of our repository libraries. If you are not near one of these libraries, you can go to a local library and ask the librarian to arrange an interlibrary loan.
