About the Maps

The geologic maps listed on this page were published by the U.S. Geological Survey and by the Pennsylvania Geological Survey. They were scanned at 300 dpi with 24 bit color matching and are stored as compressed .sid files. To view the files may require a free plug in, the ExpressView Browser Plug-in (formerly MrSID) available from LizardTech, Inc. The maps are listed by publisher then series then by their quadrangle or county name. If you do not know the 7.5 minute quadrangle name for your location, an index map is available from the Pennsylvania Geological Survey. Alternately, the Geographic Names Information System may be used to look up quadrangle names.

IMPORTANT NOTE: The tools mentioned above will give the quadrangle name at 1:24,000 scale (a 7.5 minute quad.). Many of the older maps used the 1:62,500 scale (a 15 minute quad.) therefore the quadrangle names are different. To find the 15 minute quadrangle names, use the map index provided by the Penn State University Libraries Maps Library.

The potion of the map that is visible on screen can be saved using the right-click menu item Save As..., which will bring up the Save As Dialog Box. The file can be saved in TIFF, JPEG, or BMP format.

The complete maps are also available as TIFF images, which are stored on CD-ROM. The CDs may be borrowed. FTPing of specific TIFFs is available upon request.
