Krist Ronan Anderson, 24, was last seen during a July 1998 canoe trip on the Klutina River near Copper Center, Alaska. The canoe overturned in rapids near mile 10 south of the Richardson Highway bridge; Krist was seen clinging to a boulder and was not wearing a life jacket. His companion survived but Krist was swept away by the river and never seen again.

Alaska State Troopers mounted search and rescue operations in the fast-flowing river and surrounding rugged terrain, but no sign of Krist was found. The green jacket and cotton trousers he wore that day were never recovered, and the search was eventually suspended.

The circumstances point to a sudden accident in a remote, powerful section of river; beyond what happened during the capsize, little else is known. Did anyone float the Klutina River that summer who remembers seeing a canoe overturned or other unusual activity near mile 10 south of the Richardson Highway bridge?
