With no maintenance crews available during the government shutdown, some national parks are closing campgrounds due to overflowing garbage while others are closing roads due to snowy conditions.

In Texas, officials at Big Bend National Park on Wednesday closed the Chisos Basin, Rio Grande Village, and Cottonwood campgrounds due to sanitation and resource impact concerns. The Rio Grande Village RV hookups campground, which is managed by Forever Resorts, remained open, however, the park said in a notice on its website.

Additionally, the Santa Elena Canyon Trailhead and trail was closed due to resource impact concerns, though the park didn't specify what concerns were.

In North Dakota, staff at Theodore Roosevelt National Park closed the North Unit's scenic drive Wednesday because of snowfall. In the South Unit the East River Road remained open, though the Scenic Loop Drive was closed to vehicles.

At Mount Rainier National Park in Washington state, the shutdown prompted park officials to stop traffic at Longmire, with no public access allowed to Paradise. Death Valley National Park staff put out a release urging visitors to take their trash out of the park with them. In New Mexico, the public was accessing White Sands National Monument, which was supposed to be closed to the public during the shutdown, by walking up a dune that covered a fence, according to local media.
