Search crews believe they have found the body of the 62-year-old rafter who has been missing since her commercial raft flipped near the Utah border.

Sandra "Sandy" Wolder of Aurora hasn’t been seen since around 5 p.m. Friday. The National Park Service says crews found her body Sunday afternoon.

Wolder had taken a rafting trip with Adrift Adventures when their boat hit a rock and flipped at Upper Disaster Falls. Everyone else aboard the raft made it safely back to shore.

Their raft was pinned to a rock due to the current, the NPS says.

Members of the rafting group searched the shoreline for Wolder, but it yielded no results.

Disaster Falls has a class III to IV rating depending on water level. It is located in a remote section of the Canyon of Lodore, around 7 miles from the launch location, according to the NPS.

"The staff at Dinosaur National Monument would like to express our sincere condolences to the family and friends of Sandy Wolder, as well as the rest of the members of her rafting group," the National Park Service released on Monday.
