GRAND CANYON NATIONAL PARK, Ariz. (AP) - Tourists headed to the Grand Canyon on Tuesday could find themselves turned away at the entrance gates.
National parks are scheduled to close if an agreement on the federal budget isn't reached.
Employees of Grand Canyon National Park have been told to show up to work as scheduled Tuesday but most of them would be sent home if the government shuts down.
Some of the remaining employees will be posted at the entrance gates, while others will cordon off overlooks along a state highway that will remain open to through traffic. Signs at trailheads will tell people they have to leave.
Anyone already hiking in the backcountry or rafting on the Colorado River will be able to complete their trips.
About 18,000 people visit the Grand Canyon daily in October.
