Quadrangle Index Map for Map 61

Click the area of interest on the map below for a more detailed map showing the quadrangle names. Then select the quadrangle of interest. The quadrangle maps are in portable document format (PDF).*

For some quadrangles, supplementary augmented citations are denoted by an * (asterisk). These augmentations are based on surficial geology, general geology, mineral resource, progress, special bulletins, water resource, and economic reports. Some quadrangles have multiple citations because they overlap into different counties. More information on the Pennsylvania Geological Survey series of publications can be obtained at our publications web page.
