Dataset contains point data describing the results of 1-channel and 12-channel seismic refraction studies mapped at a scale of 1:24,000, from the Maine Geological Survey. The results include the depth to the water and depth to the bedrock.
Dataset contains point data labels describing the textures of surficial sediments, independent of interpretations regarding their origin mapped at a scale of 1;24,000, from the Maine Geological Survey. Thickness of gravel, sand, silt, clay, and diamicton is shown. Data comes from auger holes, test pits, well logs, test borings, and gravel pits. Mapped at a scale 1:24,000. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Point data compiled and digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases. Point attribute table contains information on the type of data point and, where appropriate, depth to bedrock, depth to water table, well yield, and/or material type and thickness.

Dataset contains surficial geology miscellaneous point data for the quadrangle mapped at a scale of 1:24,000, from Maine Geological Survey. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Surficial geology delineated and digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases (Full description of each point type is contained in the associated attribute table).
Dataset contains text leader lines for the quadrangle mapped at a scale of 1:24,000, from the Maine Geological Survey. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases. Full description of each line type is contained in the associated attribute table.

Dataset contains line data describing the results of 1-channel and 12-channel seismic refraction studies mapped at a scale of 1:24,000, from the Maine Geological Survey. The results include the depth to the water and depth to the bedrock.
Dataset contains contact lines of significant aquifers (glacial deposits that are a significant ground water resource) for Maine mapped at a scale 1:24,000, from the Maine Geological Survey. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Aquifer boundaries delineated and digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases.
Dataset contains polygons of significant aquifers (glacial deposits that are a significant ground water resource) for Maine mapped at a scale 1:24,000, from the Maine Geological Survey. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Aquifer boundaries delineated and digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases. Aquifer polygons coded by yield expected from a properly constructed well (using the AQUIFERTYPE field or the field ATYPE = 0 area not mapped as aquifer; ATYPE = 1 10-50 gallons-per-minute; ATYPE = 2 greater than 50 gallons-per-minute; ATYPE = 3 island of non-aquifer material within an area mapped as aquifer).
