Note: Since completion of the Comprehensive Management Plan, Antelope Hill has been irreparably damaged by rock quarrying on the WMIDD property. Interpretation may still be possible on the BLM portion of the hill. Any interpretion of Antelope Hill would be coordinated in partnership with BLM and affected American Indian tribes and groups.

Any interpretation of sites associated with BLM's interpretation of the Butterfield Overland Mail route will be coordinated with BLM, affected American Indian tribes and groups, and others as appropriate.
