This dataset includes well logs used in the creation of the Olean hydrogeologic framework. Well logs were used from multiple sources (DEC, DOT, NWIS, ESOGIS, and recently digitized archived material) and were a crucial component in generating hydrogeologic layer elevations and thicknesses. Well logs are available in their original form on GeoLog Locator (https://webapps.usgs.gov/GeoLogLocator/#!/) and provided here in the digitized form (shapefiles and feature classes), which were used in the generation of the hydrogeologic framework.
This dataset includes spreadsheets with statistical data (mean and median absolute error) used in deciding which interpolation method best fit the corresponding dataset. All statistical data were paired with a visual inspection of the interpolation prior to determining the final raster product. All spreadsheets were generated using an automated python script (Jahn, 2020).
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...
This dataset includes georeferenced TIFF files from three separate reports for the Olean study area that have been digitized into feature classes within ArcGIS. Not all digitized and georeferenced data was necessarily used in the final interpolations, however they may have contributed to understanding the local hydrogeology.
This dataset includes "smoothing points" used in the creation of the Olean hydrogeologic framework. Smoothing points were manually added and were used to enhance interpolated layers using geologic assumptions and include: smoothing points for the upper and lower lacustrine confining surfaces, valley edge points, centerline bedrock points, bedrock contour points, and bedrock SSURGO points used in both the valley and upland interpolations.
