BLM - Colorado Mining Claims Closed

Description:
Shapefile Format –This data set consists of closed mining claim records extracted from BLM’s LR2000 database. These records contain case attributes as well as legal land descriptions for each parcel of land involved in the individual cases. Shapefiles are created by matching LR2000 land descriptions against the smallest feature possible in the GIS representation of the Public Land Survey System (PLSS) https://navigator.blm.gov/data?keyword=plss&fs_publicRegion=Colorado. When a direct match is found, the corresponding polygon in PLSS is used as a template to create a new feature in the output shapefile. The new feature is not a representation of the mining claim boundaries. Multiple mining claims may be located within the same area. The resulting GIS dataset has been projected to NAD83/UTM13N and dissolved on case-level attributes.
