The National Park Service is investigating reports of vandalism — acrylic painting on rocks — in Joshua Tree and at least ten national parks in Arizona, California, Colorado, Oregon, and Utah. Details are not yet available because the case is under investigation, but the vandalism is believed to have occurred in Grand Canyon, Yosemite, Death Valley, Sequoia-Kings Canyon, Joshua Tree, Rocky Mountain, Crater Lake, Bryce Canyon, Zion and Canyon lands. A National Park Service spokesperson said, “There are forums for artistic expression in national parks because national parks inspire artistic creativity. These images are outside that forum and outside the law.” See the link below for more information on the serial investigation.
