Maps at a scale of 1:24,000 are used to identify surficial geologic materials and resources, to identify and evaluate physical hazards, and to evaluate groundwater resources. Digital data from Wright, S., 2022, Surficial Geologic Map of the Brookfield 7.5 Minute Quadrangle, Vermont: Vermont Geological Survey Open File Report VG2022-1, 1:24,000-Scale. Data may include surficial geologic contacts, isopach contours lines, bedrock outcrop polygons, bedrock geologic contacts, hydrogeologic units and more. The surficial geologic materials data at a scale of 1:24,000 depict types of unconsolidated surficial and glacial materials overlying bedrock in Vermont. Data is created by mapping on the ground using standard geologic pace and compass techniques and/or GPS on a LiDAR or USGS 1:24000 topographic base map. The materials data is selected from the Vermont Geological Survey Open File Report (OFR) publication (https://dec.vermont.gov/geological-survey/publication-gis/ofr). The OFR contains more complete descriptions of map units, cross-sections, isopach maps and other information that may not be included in this digital data set.
