 The Salt Lake City Fire Department released a statement over the weekend identifying Harp as a captain and a 27-year veteran of the department. The group was going through the Hell's Half Mile Rapid on the Colorado side of the monument. The spot was known as a Class 3 to Class 4 rapid, meaning a spot from beginning to advanced level for rafting. At one point, the raft became pinned on a rock and officials said that Harp went missing.
