The Timbisha Shoshone Tribe just held an event to commemorate 25 years since the landmark legislation outlining a historic co-stewardship agreement between the tribe and the National Park Service in Death Valley. The tribe’s name is on the entrance sign to the park. At the same time, the Trump administration is calling for the removal of informational plaques in the visitor center that tells the tribe’s story. The sign’s removal is one of almost 20 at National Park sites around the country, including Little Big Horn Battlefield National Monument, the site of the allied tribes’ decisive victory over George Armstrong Custer and U.S. Army’s 7th Cavalry Regiment. We’ll talk to tribal representatives about how the information in National Parks was developed and what message removing it sends.
