This vector dataset is part of the digital version of the map titled Preliminary bedrock geology of Dane County, Wisconsin, by B.A. Brown, K. Massie-Ferch, and R.M. Peters (Open-File Report 2013-01). The map and cross sections are based on fieldwork and analysis of subsurface data by the authors between 1995 and 1996, and on earlier field mapping by P.G. Olcott (1972). As a set, they depict basic information about the composition, distribution, and thickness of bedrock formations that are exposed at the land surface or are penetrated in the subsurface by municipal wells, domestic water wells, and engineering test borings. They are intended to provide the basic geologic framework required for groundwater and mineral resource analysis, and land-use planning. Understanding the nature of the bedrock is important for both environmental and economic reasons.
These point features represent nearly 8000 locations (wells, outcrops, and quarries) used to map the bedrock geology of Dane County, Wisconsin. This dataset was developed from sources of varying map scales and time periods and may not be sufficient for site-specific applications.
Unpublished field maps, notes, and geologic compilation work done by P.G. Olcott from 1970 to 1972 provided an invaluable resource throughout this project. The authors also acknowledge the early contributions to mapping in southwestern Dane County, and regional geophysical analysis provided by M.G. Mudrey, Jr, and cartographic work done by M.L. Czechanski; and digitization of outcrops by A.M.K. Fritz (1995). Cartography and GIS data analysis for WOFR2013-01 were provided by K.C. Roushar and P.R. Schoephoester.

The data have not been extensively reviewed for conformity with the Wisconsin Geological and Natural History Survey standards and nomenclature.

The geologic map (Plate 1) illustrates the distribution of geologic formations at the bedrock surface. The cross sections (Plate 2) depict the thickness and configuration of these formations down to the crystalline basement, and the thickness of overlying Quaternary deposits. The map and sections are based on fieldwork and analysis of subsurface data by the authors from 1995 to 1996, and on earlier field mapping by P.G. Olcott (1972). Subsurface data included WGNHS geologic logs, WDNR well construction reports, and engineering borings. Well locations, outcrop locations, and other geologic control points are shown on Plate 1. These data represent work performed by the Wisconsin Geological and Natural History Survey and are released to the open files in the interest of making the information readily available. The data have not been extensively reviewed for conformity with the Wisconsin Geological and Natural History Survey standards and nomenclature.

The dataset was developed from sources of varying map scales and time periods. Initial data capture was in ArcInfo coverage format, subsequently imported to ArcGIS geodatabase format (WTM83 HARN), and exported to shapefiles for distribution. Subsurface data were compiled from WGNHS and Wisconsin DNR well construction reports and from WGNHS geologic logs. Those records provided location information, descriptions of geology, and depth to bedrock. Outcrops are a subset of the data digitized circa 1995 from P.G. Olcott's field maps (1972)--topographic, 1:24,000 scale or 1:62,500 scale (northern border of the county). Notes indicate that only outcrop locations with formation designation were digitized. Quarry locations are a subset of the WGNHS Mines, Pits, and Quarries database.
