These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains polygons depicting areas of this unit estimated to have greater than 10,000 mg/L of TDS.

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains polygons of geologic units forming the top of the Floridan aquifer system. Polygon regions were modified from U.S. Geological Survey Professional Paper 1403B (Miller, 1986).
Hand specimens of rocks collected in and around Marathon County as part of a bedrock mapping project in the 1970s and 1980s. Specimens were collected by P.E. Myers and UW-Oshkosh geologist Gene LaBerge as part of the field work supporting WGNHS publication Information Circular 45: Precambrian Geology of Marathon County, 1983. The collection consists of about 1500 specimens taken from approximately 580 outcrop locations.
