Detailed geologic mapping geodatabase for the Blue Ridge Parkway in Virginia with station point photographs The US Geological Survey, in cooperation with the National Park Service, mapped 35 7.5-minute quadrangles, within a 2-mile-wide+ corridor centered on the Parkway, from BLRI (Blue Ridge Parkway) Mile Post (MP) 0 near Afton, Virginia southward to MP 218 at Cumberland Knob, approximately 1.3 km south of the Virginia – North Carolina State Line. Detailed bedrock geologic mapping for this project was conducted at 1:24,000-scale by systematically traversing roads, trails, creeks, and ridges within and adjacent to the 2-mile-wide+ corridor along the 216.9-mile length of the BLRI in Virginia. Geologic data at more than 23,000 station points were collected during this project (September 2009 – February 2014), with approximately...

Vance Birthplace, Fewer tags Offshore of Fire Island Inlet, New York These data are from a 1998 multibeam survey of the sea floor offshore of Fire Island Inlet, New York. There are five datasets: bathymetry grid, shaded-relief image, backscatter intensity image, shaded-relief colored by backscatter intensity image, and trackline navigation. The bathymetry shows the shape of the sea floor. Of particular interest are the size, shape, and orientation of bed forms that may indicate sediment movement. The shaded-relief image provides a visualization of the bathymetry that accentuates small features that cannot be effectively shown as contours alone. The image of backscatter intensity provides qualitative information on the sediment texture and roughness of the sea floor. The image of...

Dataset includes sample site locations and information, analytical method information, water sample pharmaceutical concentrations and summary statistics, and corresponding watershed land-use-land-cover data and data dictionary.

In this study conducted by the U.S. Geological Survey in cooperation with Colorado State University, the objectives were to model streamflow metrics on small, ungaged streams in the Upper Colorado River Basin and identify streams that are potentially threatened with becoming intermittent under drier climate conditions. The Upper Colorado River Basin is a region that is critical for water resources and also projected to experience large future climate shifts toward a drying climate. A random forest modeling approach was used to model the relationship between streamflow...
