Second Geological Survey of Pennsylvania (vols. K - Z)

Described in 1924 as “the most remarkable series of reports ever issued by any survey”, the Second Geological Survey of Pennsylvania (1874-1889) produced an unprecedented volume and quality of geologic reports. With over 80 texts, nearly 600 accompanying maps and illustrations, a hand atlas, a six-volume grand atlas, and miscellaneous other publications, the Second Survey contains a treasure trove of geologic, economic and historic information about Pennsylvania during the Golden Age.

The publications of the Second Survey are available as part of the Pennsylvania Geology Digital Collection.
