SALT LAKE CITY — Officials are warning Canyonlands National Park visitors that part of the White Rim trail in eastern Utah is impassable because of flooding from a nearby river.

Canyonlands National Park official Mary Wilson said on Wednesday that a combination of heavy rain and snow runoff has caused the Green River to rise.

Wilson says this type of water level rise is fairly standard for this time of year. She says she hasn’t heard of anyone being stranded because of the flooding.

Park service officials say they don’t know exactly how long the western part of the trail will be impassable.
