Rolfe Hoyer lost his life fighting the Slaughter Fire in the Apache Forest on May 19, 1967. Born on a farm near Kalamazoo, Mich., he early developed an interest in the outdoors, and when he entered Michigan State University he studied forestry, and received his degree in that field. He joined the Forest Service in 1956 on the Coconino National Forest and later became an assistant District Ranger and then Ranger on the Mayhill District of the Lincoln National Forest in New Mexico. In 1962, Rolfe Hoyer was assigned to the Apache National Forest, where he served with distinction as recreation and lands staff officer until his untimely death.
