Carter, M.W., Crider, E.A., Southworth, C.S., and Aleinikoff, J.N., 2016, Detailed geologic mapping geodatabase for the Blue Ridge Parkway in Virginia with station point photographs: U.S. Geological Survey data release,


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 19,500 included [...]

The geologic map database for the Blue Ridge Parkway can be utilized to address numerous county and state, land-use, and environmental issues. Possible applications of this database include the study of landslide hazards, groundwater resource issues, land-use planning for growing communities, and further studies related to earthquake hazards. These data can also be used to study the close association between bedrock geology, overlying soils and surface ecology. All of these applications require accurate, concise, and user-friendly geologic map data to produce viable derivative products and to enable sound land-use decisions.
