Site Mapper

NILS GeoCommunicator's Site Mapper is an interactive map used to graphically display abandoned mines and BLM sites including recreation, administrative, campgrounds, and buildings.

Site Mapper displays the location of the sites by the use of latitude and longitude.

Users can overlay the sites along with BLM issued land and mineral authorizations, mining claims, land and mineral title records, roads, surface management agency data, impaired watersheds, and Section 303 listed waters as well as many other reference themes and base maps.

Abandoned mines are dangerous STAY OUT! STAY ALIVE!

Source of the Data:

Facility Asset Sites come from the BLM's Facility Asset Management System (FAMS) which tracks BLM owned facilities including recreation, campgrounds, administrative sites, and buildings.

National Mine Land Inventory Data comes from many different sources as describe below. If you have questions concerning a site from another agency, please contact that agency. Many of the latitude and longitudes are approximate locations. Please read the data disclaimer.

BLM Coal/Non Coal comes from the BLM’s Protection and Response Information System (PRIS) database containing over 11,000 records updated daily. This system was developed in 2004 and deployed in February 2005. It replaces the BLM's Abandoned Mine Land Information System (AMLIS). BLM data includes the status of the site:

  • Red on the map symbol indicates the verification process has not been started or completed to determine if there is a physical hazard or an environmental problem at the site.
  • Yellow on the map symbol indicates: Planned - site verification has been done and the site is in the planning stages for remediation/cleanup or In Progress - site remediation phases are ongoing.
  • Green on the map symbol indicates: No Action – site doesn't need any remediation or cleanup or Completed – all phases of site remediation/cleanup are complete.
