From the US Bureau of Mines map publication, "Availability of Federally Owned Minerals for Exploration and Development in the Western United States". The Bureau of Mines inventoried Federal mineral land in Wyoming and assessed the availability of this land for mineral exploration and development as affected by legal status and agency management practices. To illustrate the impact that various Federal land use decisions have on the mineral industry, the USBM also identified and ranked known mineral deposit areas (KMDAs)-i.e., areas having past or present mineral production and /or known mineral resources- and compared these areas spatially with availability of Federal mineral lands. Most Federal minerals, except...

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
