Description
This report with its accompanying 1:24,000-scale geologic maps describes the nature and distribution of rock formations and surficial deposits in the vicinity of Berwick, northeastern Pennsylvania. The Berwick area encompasses approximately 56 square miles within what is now called the Ridge and Valley physiographic province in Luzerne and Columbia Counties. The area of study lies on the crest of the Berwick anticlinorium (one of the major rock fold structures in the Pennsylvania Appalachians) and is situated at the edge of the great “terminal moraine,” which was deposited by glacial ice and meltwater streams at the end of the Ice Age. This geologic setting has had a profound effect on land use, mineral resources, and environmental conditions. The report focuses on the influence of geology on groundwater occurrence and quality, cut-slope stability, excavation difficulty, foundation stability, and waste disposal. The vast sand and gravel resources of the area are described, and their geologic significance is explained.
