A Utah man who died in a rafting accident at Dinosaur National Monument in Colorado has been identified as a 27-year veteran of the Salt Lake City Fire Department.

Michael Harp, 54, was part of a group taking a private permitted rafting trip down the Green River in the Canyon of Lodore around 4 p.m. Thursday when their boat became stuck on a rock in the rapid known as Hells Half Mile, the U.S. National Park Service said.

Monument staff responded to the rafting accident and learned that Harp was missing and believed to be pinned under the raft. The rafting group dislodged the boat from the rock, but officials said Harp was unresponsive and “drifted downriver.”

Harp had been wearing a life jacket but lost it by the time the group unpinned the boat, according to the NPS.

Dinosaur National Monument is spread over 210,000 acres across Colorado and Utah. While best known for a quarry that holds preserved dinosaur fossils, whitewater rafters from around the world are attracted to the monument’s Green and Yampa rivers that cut though its famed canyons.
