Most national parks and monuments remain open but with no staffing. Campgrounds, toilets and gift shops remain closed.

America's national parks and monuments might technically still be open in the ongoing partial government shutdown, but with little-to-no staff and no one maintaining roads during winter weather, visitors of some parks do so at their own risk.

Most of the 58 national parks and national monuments remain open but with little-to-no staffing, per the .

That means toilets, campgrounds, gift shops and any other facilities at parks that require staffing are closed.

“Effective immediately upon a lapse in appropriations, the National Park Service will take all necessary steps to suspend all activities and secure national park facilities that operate using appropriations that are now lapsed, except for those that are essential to respond to emergencies involving the safety of human life or the protection of property,” according to the plan.

Gift shops, lodging and gas stations that don't require federal employee assistance will remain open.

With no staffing to keep roads clear, visitors may also have trouble navigating some parks like Yellowstone National Park or Yosemite National Park after snow has fallen.

Volunteers are helping out in some parks like California's Joshua Tree National Park.

Rand Abbott, a Joshua Tree rock-climber and volunteer, began at park toilets as soon as the shutdown began last week.

"I've gone through 500 rolls of toilet paper," Abbott told MSN. "And I've been emptying all the trash cans that are there and putting bags in. And then I've been giving out trash bags to people. I've probably put 60 hours in."

There are also reports of people not abiding by park rules. Strings of Christmas lights reportedly have been hung on the Joshua Trees, which are not to be touched.

"It's a free-for-all in there. Absolutely ridiculous," Joe De Luca, a sales associate at Nomad Ventures in downtown Joshua Tree, told MSN.

While technically open, Rocky Mountain National Park had to close some access roads this week because of snow, the Associated Press reports. Visitors can still access the roads on foot or bicycle.

“Visitors from around the world who have planned their trips to our national parks months in advance now face the possibility of disruption and disappointment when they arrive at parks only to find , locked restrooms and unplowed roads,” Theresa Pierno, the president of the National Parks Conservation Association (NPCA), said in a statement.

“Local businesses and park concessioners also face the possibility of having to re-route passengers to other tours or cancel excursions altogether, threatening $18 million in economic activity that our national parks support on average each day during the month of December," Pierno added.

Some states have made their own contingency plans to keep parks open.

Arizona Gov. Doug Ducey said in a press release Friday that the Grand Canyon would remain open to the public and fully staffed under the , an executive order signed by the governor in February 2018 that would keep the national park open during any government shutdown.

"Regardless of what happens in Washington, the Grand Canyon will not close on our watch," Ducey said. "Arizona knows how to work together. We have a plan in place and we're ready to go. If you have plans to visit the Grand Canyon over the weekend, keep 'em. The Grand Canyon will remain open."

The also remain open and fully staffed thanks to New York state funding, according to the U.S. National Park Service page for the sites.

In Utah, Zion, Arches and Bryce Canyon national parks after Gov. Gary Herbert authorized $80,000 Thursday to fund the three parks for the rest of the year if a shutdown occurred.

Other parks and monuments aren't faring as well because of a lack of staffing. in Maryland, the birthplace of the US national anthem, remains closed.

Tours and ranger talks have been canceled throughout the parks system.

The partial government shutdown took effect at midnight Friday after Congress failed to negotiate a temporary funding solution for nine federal agencies, including the Department of the Interior.

The negotiations stalled over President Donald Trump's $5.7 billion request to fund a border wall.

Due to the impasse among legislators which forced the shutdown, more than 800,000 federal workers are now furloughed or are required to work without pay through the holidays, including 3,600 forecasters with the National Weather Service.

Other "essential" federal employees that are required to work without pay throughout the shutdown include 42,000 members of the U.S. Coast Guard, thousands of law enforcement officers and 5,000 firefighters with the U.S. Forest Service.
