Activists lobby to save Clark County petroglyphs from dam silt
Conservation advocates are sick of all the silt. They’re calling on the Bureau of Land Management to fix the dam problem. Conservation activists are urging the agency to address issues with a historic dam that is burying petroglyphs in the Arrow Canyon Wilderness. “If we don’t do something now, all of that stuff you saw in the wash will be gone,” Terri Robertson said. “You don’t know how many archaeological sites are buried under that silt,” Elaine Holmes said.
