Human feces, overflowing garbage, illegal off-roading and other damaging behavior in fragile areas were beginning to overwhelm some of the West's iconic national parks on Monday, as a partial government shutdown left the areas open to visitors but with little staff on duty.
"It's a free-for-all," Dakota Snider, 24, who lives and works in Yosemite Valley, said by telephone Monday, as Yosemite National Park officials announced closings of some minimally supervised campgrounds and public areas within the park that are overwhelmed.
"It's so heartbreaking. There is more trash and human waste and disregard for the rules than I've seen in my four years living here," Snider said.
The 10th day of the partial federal government shutdown, which has forced furloughs of hundreds of thousands of federal government employees, has left many parks without most of the rangers and others who staff campgrounds and otherwise keep parks running.
Unlike shutdowns in some previous administrations, the Trump administration was leaving parks open to visitors despite the staff furloughs, said John Garder, senior budget director of the nonprofit National Parks Conservation Association.
"We're afraid that we're going to start seeing significant damage to the natural resources in parks and potentially to historic and other cultural artifacts," Garder said. "We're concerned there'll be impacts to visitors' safety."
"It's really a nightmare scenario," Garder said.
Spokespeople with the Interior Department did not immediately return emails seeking comment on Monday.
National Park Service spokesman Jeremy Barnum had said as the shutdown took hold that "national parks will remain as accessible as possible while still following all applicable laws and procedures."
