Bertha Genieve Demoski, 38, disappeared on a late September day in 1960 while traveling by boat on the Yukon River between the small Yukon communities of Nulato and Ruby. She was with four companions—Claude Demoski, Emmett Nollner, Leo Demoski, and Harry Pitka—when the group set off; the trip was planned but specifics about their vessel and exact departure time are scarce. The group was reported missing to the Alaska State Troopers on September 26, 1960, and a search followed, but no wreckage, personal effects, or other physical evidence was ever reported recovered.

The disappearance is remembered in the communities of Nulato and Ruby and stands as one of several unsolved cases tied to the region’s challenging wilderness and river conditions.

Did anyone in the community have contact with Bertha or the others before they left Nulato, or know details about the boat they were using?
