In 2017, President Trump ordered the review of 27 national monuments, mostly in western states, by Interior Secretary Ryan Zinke.

The White River Narrows Archeological District in The Basin and Range National Monument, contains a large concentration of prehistoric rock art, including panels over 4,000 years old. The 704,000 acres include Garden Valley and Coal Valley; the Worthington Mountains, Golden Gate Range, Seaman Mountains, and Mount Irish Range; the Hiko Narrows and White River Narrows; and the Shooting Gallery rock art site.
