A geodatabase of Surficial Geology of the Allentown 30x60-Minute Quadrangle in Pennsylvania digitized from the original map of Braun, 1996

This Scientific Data Release is a spatial geodatabase representation of Braun, D. D., 1996, Surficial geology of the Allentown 30x60-minute quadrangle: Pennsylvania Geological Survey, 4th ser., Open-File Report 96–48, 17 p., 1 map, scale 1:100,000. These geospatial data depict surficial geologic materials in the Pennsylvania portion of the Allentown 30 x 60-minute quadrangle in eastern Pennsylvania.The map area shows the effects of at least three Pleistocene glacial advances. The report map is a compilation and revision of published and unpublished, 1:24,000-scale, detailed-reconnaissance maps. Types of surficial geologic units include 14 anthropogenic, 8 alluvial or wetland, 16 colluvial, and 12 Wisconsinan, Illinoian, or pre-Illinoian glacial. Eleven types of bedrock units are shown, defined by rock type and color.
