Claude Demoski, 45, disappeared on September 25, 1960, after setting out by boat from the Athabascan village of Nulato for Ruby on the Yukon River. He was traveling with relatives Bertha Demoski, 38, and Leo Demoski, 48, and two other community members, Harry Pitka, 39, and Emmett Nollner. The five never arrived in Ruby and no wreckage, belongings, or other physical evidence were reported found.

The Alaska State Troopers opened a case on September 26, 1960, but the file contains little beyond the names, the date of last contact, and the fact the party was last seen traveling by boat. The river and surrounding wilderness remain the only context for what might have happened, yet no confirmed traces have surfaced to explain their disappearance.

Did anyone in Nulato or Ruby remember seeing that boat or the group on September 25, 1960?
