Steve Wayne Keiner went missing on April 8, 1992, while operating a snow machine on the Gakona Glacier, about 22 miles northeast of Summit Lake near milepost 195 of the Richardson Highway. He was 46, Caucasian, 5 feet 11 inches, about 160 pounds, with hazel eyes and graying hair. Reports say he and his machine plunged into a deep crevasse; the fall was sudden and left no opportunity for rescue.

At the time he was believed to be wearing black bib pants, a blue jacket, bunny boots, and an orange knit hat. The Alaska State Troopers documented the disappearance the same day; the glacier’s shifting ice and the depth of the crevasse made recovery efforts perilous and the crevasse ultimately became his presumed resting place.

Does anyone have information about Keiner’s last outing in the Glennallen area or knowledge of travel on the Gakona Glacier that day?
