Arizona Bureau of Land Management rangers discovered the vandalism late last year at the large rock art site located on BLM-administered lands. They say the damage includes rolled boulders and fractured petroglyphs.
Archaeology located on public lands is protected by federal law. Authorities say defacement is punishable by up to a $100,000 fine and/or imprisonment for up to five years for each offense.
Sears Point Archaeological District is located about 75 miles east of Yuma. The site consists of petroglyphs, trails, rock alignments and other features which extend for miles along the southern bank of the Gila River
