A 17-year-old Sandy girl died Saturday in a hiking accident just outside Canyonlands National Park when she fell off a cliff near Gooseneck Overlook.

She was identified as Jessica Welker, a daughter of Judy and Dave Welker of Sandy.San Juan County sheriff's Sgt. Rudy Cook said the girl was exploring and taking pictures with three other people, all of Salt Lake City, when she fell about 60 to 70 feet off a cliff near the Gooseneck Overlook, about eight miles from the Island in the Sky Visitors Center.

The officer said Welker's girlfriend was taking pictures about 25 to 30 yards away when she saw the teen fall over the cliff. Cook said an air ambulance was dispatched, but the girl died before it could reach the scene.
