The National Mine Map Repository (NMMR) maintains point locations for mines appearing on maps within its archive. This dataset is intended to help connect the Office of Surface Mining Reclamation & Enforcement, other federal, state, and local government agencies, private industry, and the general public with archived mine maps in the NMMR's collection. The coordinates for mine point locations represent the best information the NMMR has for the location of the mine. As much as possible, the NMMR strives to find precise locations for all historic mines appearing on mine maps. When this is not possible, another feature as close to the mine as is known is used. This information is reflected in the mine point symbols. However, the NMMR cannot guarantee the accuracy of mine point locations or any other information on or derived from mine maps.The NMMR is part of the United States Department of the Interior, Office of Surface Mining Reclamation and Enforcement (OSMRE). The mission of the NMMR is to preserve abandoned mine maps, to correlate those maps to the surface topography, and to provide the public with quality map products and services. It serves as a point of reference for maps and other information on surface and underground coal, metal, and non-metal mines from throughout the United States. It also serves as a location to retrieve mine maps in an emergency. Some of the information that can be found in the repository includes:Mine and company names, Mine plans including mains, rooms, and pillars, Man-ways, shafts, and mine surface openings. Geological information such as coal bed names, bed thicknesses, bed depths and elevations, bed outcrops, drill-hole data, cross-sections, stratigraphic columns, and mineral assays. Geographical information including historic railroad lines, roads, coal towns, surface facilities and structures, ponds, streams, and property survey lines, gas well and drill-hole locations. Please note: Map images are not available for download from this dataset. They can be requested by contacting NMMR staff and providing them with the desired Document Numbers. NMMR staff also have additional search capabilities and can fulfill more complex requests if necessary. See the NMMR website homepage for contact information: https://www.osmre.gov/programs/national-mine-map-repositoryThere is no charge for noncommercial use of the maps. Commercial uses will incur a $46/hour research fee for fulfilling requests.

The sediment map of the Continental Margin Mapping Program (CONMAP) series is a compilation of grain-size data produced by the U.S. Geological Survey (USGS) and includes both published and unpublished studies. Sediment was classified using the 1929 Wentworth grain-size scale and the 1954 Shepard scheme of sediment classification. Certain grain-size categories are combined because of the paucity of some sediment textures. True boundaries between sediment types are highly irregular or gradational. This is due to textural variability not characterized at this scale, and because the accuracy of the navigational systems used during the earlier studies is limited. Sediment classification reflects the dominant surficial sediment type for that area and does not infer that other sediment types are not present. Blank parts of the maps indicate areas where data are insufficient to infer sediment type. This data layer is supplied primarily as a gross overview and to show general textural trends.
