Description: The Subsurface Mineral Estate (SSME) dataset depicts Federal mineral interest in the State of Wyoming and classifies these lands by subsurface mineral ownership, Federal or Indian trust, types of minerals owned, and percent ownership within the State of Wyoming. Federal Mineral Estate refers to the mineral estate reserved to the Federal government or a Federally recognized tribe. The SSME data depicts which minerals are reserved, whether they are reserved to the Federal government or held in trust for a tribe, and the percentage of said minerals reserved. The SSME data does not depict private mineral ownership patterns. This data set is a result of compiling differing source materials of various vintages. Source material examples used to create and maintain this dataset include BLM 100k Subsurface Maps, Oil and Gas Plats, Coal Plats, Public Land Survey GIS Data (CadNSDI v.2.0), Field Office GIS Data, Compiled 24k USGS Maps, and Land Records.
