This digital geologic map compilation presents new polygon(i.e., geologic map unit contacts), line (i.e., fault, foldaxis, and structure contour), and point (i.e., structuralattitude, contact elevations) vector data for the Jasper 7 1/2'quadrangle in northern Arkansas. The map database, which is at1:24,000-scale resolution, provides geologic coverage of anarea of current hydrogeologic, tectonic, and stratigraphicinterest. The Jasper quadrangle is located in northern Newtonand southern Boone Counties about 20 km south of the town ofHarrison. The map area is underlain by sedimentary rocks ofOrdovician, Mississippian, and Pennsylvanian age that weremildly deformed by a series of normal and strike-slip faults andfolds....

The geographic information system (GIS) format spatial data set of vegetation for Buffalo National River (BUFF) was created for the National Park Service (NPS) Vegetation Inventory Program (VIP). The BUFF administrative boundary covers an area of nearly 38,000 ha. The map classification scheme used to create the vegetation data set is designed to represent local vegetation types at the finest level possible using the National Vegetation Classification Standard (NVCS) Version 2. Physiognomic information was also recorded, including height (woody vegetation), canopy density, and coverage patterns. The vegetation data set was developed by interpreting aerial photographs collected in October of 2006 and extensive field...

This dataset accompanies publication 'Isotopic constraints on middle Pleistocene cave evolution, paleohydrologic flow, and environmental conditions from Fitton Cave speleothems, Buffalo National River, Arkansas', published as a contribution to USGS Scientific Investigations Report 2017-5023 associated with the 2017 USGS Karst Interest Group meeting in San Antonio, TX.

This dataset includes tables of U- and Th-isotopic data used to calculate uranium-series age estimates (230Th/U method) and initial 234U/238U activity ratios for samples of tufa mounds formed by groundwater seepage. In addition, data include 87Sr/86Sr and 234U/238U values determined for spring discharge and streamflow collected from sites in the vicinity of Buffalo National River.
