High water on the Green River has submerged the western part of Utah's White Rim trail in Canyonlands National Park, potentially stranding visitors touring the famed 100-mile loop popular with mountain bikers and ATV riders.

The river rose above 20,000 cubic feet per second on Monday as spring runoff surged from surrounding mountains and flooded the two-track trail between Potato Bottom and Labyrinth campsites, according to the National Park Service.

This means rim travelers on a clockwise tour will not be able to exit from Mineral Bottom until after flows drop to at least 14,000 cubic feet per second.

"We do not know how long it will remain impassable. If your trip has you entering or exiting through this area, please plan accordingly," the park service said in a media advisory.

Up-to-date flow information is available online from the U.S. Geological Service. Permit holders are encouraged to call Island in the Sky visitor center, 435-259-4712, to get current road conditions and river information before starting their trips.
