John Squires, 71 and from California, disappeared on June 20, 2018 during a six-day float on American Creek in Katmai National Park. He and two experienced friends launched a raft on a creek that was running unusually high and fast after storms. Their raft struck a sweeper and overturned, throwing all three into the frigid, fast-moving water.

Both companions reached opposite shores, but John — not wearing a personal flotation device — was last seen swimming downriver toward the shoreline and then was carried out of sight. A multi-agency search by the National Park Service, the U.S. Coast Guard and Alaska State Troopers, with volunteer help, used air and raft searches; no trace of him was found and authorities later called off the official search. John is presumed drowned and his body has not been recovered.

Does anyone have information about that June 20, 2018 trip on American Creek or remember seeing anything that could help explain what happened?
