This dataset is a statewide polygon coverage of sand, gravel, and stone resources. This database includes the best data available from the VT Agency of Natural Resources and VTrans quadrangle maps where sand and gravel locations are noted. Sources are maps from "Geology for Environmental Planning" booklets prepared by Charles G. Doll in the 1970's, the data were derived from USGS sources. VCGI expects that this data will be updated and added to by other sources, but it is the most complete/accurate data available to us at this time.

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information.
