About this dataset

Digital hydrogeologic datasets were developed for the Olean study area in upstate New York in cooperation with the New York State Department of Environmental Conservation. These datasets define the hydrogeologic framework of the valley-fill aquifer and surrounding till-covered uplands within the study area. Datasets include: bedrock elevation raster, lacustrine silt and clay top and bottom elevation rasters (where present) for the main lacustrine unit, lacustrine silt and clay top and bottom elevation rasters (where present) for an upper lacustrine unit, LIDAR minimum elevation raster, lacustrine extent polygons, valley-fill extent polygon, and surficial geology polygons. Elevation layers were interpolated at 125-foot discretization to match what was done in previous work.
