Boundaries of lead agencies responsible under SMARA for regulating mine reclamation.

This dataset contains mining claim cases with the case disposition (status) of anything other than closed from US Bureau of Land Management's, BLM, Mineral and Land Record System(MLRS). The BLM only requires that mining claims be identified down to the affected quarter section(s)—as such, that is what the MLRS research map and public reports will reflect, most commonly. Claim boundaries, as staked and monumented, are found in the accepted Notice/Certificate of Location as part of the official case file, managed by the BLM State Office having jurisdiction over the claim.The geometries are created in multiple ways but are primarily derived from Legal Land Descriptions (LLD) for the case and geocoded (mapped) using the Public Land Survey System (PLSS) derived from the most accurate survey data available through BLM Cadastral Survey workforce. Geospatial representations might be missing for some cases that can not be geocoded using the MLRS algorithm.,
