Turner, N.L., Knierim, K.J., Kresse, T., 2016, Sinkholes and Springs of the Ozark Physiographic Province, northern Arkansas, from Topographic Maps: U.S. Geological Survey data release, http://dx.doi.org/10.5066/F7XK8CNZ.

This dataset is a compilation of karst features (sinkholes and springs) digitized from U.S. Geological Survey (USGS) topographic maps over the Ozark Plateaus Physiographic Province (Ozarks) of northern Arkansas. Both historical (1940s through 1980s) and recent (2014) topographic maps were used in the creation of the dataset. Sinkhole polygons were digitized from enclosed depressions (identified by hachure marks) on the USGS topographic maps, and are additionally represented as a centroid point that was defined from the polygon. Springs were digitized as points from labeled spring locations on the topographic maps. Attributes for the karst features include the type of feature (spring or sinkhole), name of the county and quadrangle of location, topographic map year, coordinates (latitude and longitude), area (for sinkhole polygons), and name (for springs, where a name occurred on the topographic map). No digital dataset of this type existed previously for the Arkansas Ozarks, and in karst regions (landscapes dominated by bedrock dissolution), the interconnectedness of groundwater and surface water is dynamic and complex. With this dataset, quantitative, regional-scale investigations of water quality, karst science, and geomorphology can be completed.
