Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers within Northern Medina County, Texas at 1:24,000 This data release supports the U.S. Geological Survey Scientific Investigation Map (SIM) by Clark and others (2020) by documenting the data used to create the geologic maps and describes the geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers for a 442 square-mile area in northern Medina County in south Texas. The karstic Edwards and Trinity aquifers that are the subject of the SIM by Clark and others (2020) are classified as major sources of water in south-central Texas by the Texas Water Development Board (George and others, 2011). The geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers largely control groundwater flow paths and storage in northern Medina County...

The geophysical log data were collected by different Federal, state, and local agencies throughout the area and were obtained from three sources: Hart and Clark (2008), the Mississippi Department of Environmental Quality (MDEQ) (Mississippi Department of Environmental Quality, 2019), and the Louisiana Department of Natural Resources (LADNR). The log data generally consisted of either scanned .jpg or .tif images of the original log. The data were digitized...
