The partial government shutdown has forced closures and reductions in staffing and services at some of the iconic national parks in California.
From the rugged Santa Monica Mountains to the dramatic landscape of Yosemite National Park and the towering trees of Redwood National Park, visitors are likely to notice the changes. The parks have been left without most of the rangers and staff members who help maintain and protect the state's natural wonders.
"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," John Garder, senior budget director of the nonprofit National Parks Conservation Association, told The Associated Press. "We're concerned there'll be impacts to visitors' safety.
"It's really a nightmare scenario."
Minimally supervised campgrounds, reduced visitor services and the elimination of maintenance services at restrooms are some of the ways the shutdown has taken a toll. At Sequoia and Kings Canyon parks, overflowing trashed and human waste forced a complete closure Thursday.
Below, a look at how the parks have been affected by the shutdown as it continues for nearly two weeks.
