To redesignate the Cottonwood Visitor Center at Joshua Tree National Park as the "Senator Dianne Feinstein Visitor Center".

HR 8258 would rename the Cottonwood Visitor Center at Joshua Tree National Park to the "Senator Dianne Feinstein Visitor Center." The bill requires all official U.S. references in laws, maps, regulations, and documents to use the new name. This is a purely administrative renaming with no policy changes or direct impact on citizens or programs. It honors Senator Feinstein through a permanent naming designation at a national park facility.
