DINOSAUR — Searchers have found the body of a rafter missing in the Green River near the Colorado-Utah border since Friday.

The body of 62-year-old Sandra Wolder of Aurora, Colorado was found Sunday trapped underwater in the roots of a large downed tree in the river in Dinosaur National Monument.

Authorities say Wolder fell in the water after a commercial raft she was riding on flipped after hitting a rock in a remote part of the Canyon of Lodore. She was the only rafter who didn’t make it to shore.

The raft flipped in a section of the river called rated between intermediate and advanced, depending on river levels. It was named Disaster Falls by Maj. John Wesley Powell after one of his wooden boats wrecked there in 1869.
