Gary James Marshall, 35, vanished on April 7, 1980, while traveling by snow machine from the upper Skilak landing toward Caribou Island on Skilak Lake near Soldotna, Alaska. He was wearing a bulky blue parka with a fur-trimmed hood and reportedly wore a gold ring with a garnet stone on his right hand and possibly a gold Timex watch. He was six feet tall with brown hair, hazel eyes, a scar near his right eye, a scar on his right hand, and an unknown tattoo on his left hand.

Gary and his snow machine disappeared during early spring conditions when the lake ice was thinning. The Alaska State Troopers investigated, and the prevailing belief is that his machine broke through the ice and he drowned, though no wreckage or body is reported in this account. His disappearance remains unresolved and open in the memory of family and the Soldotna community.

Did anyone who traveled Skilak Lake in early April 1980 or who knew Gary notice anything that could shed light on what happened that day?
