In late September 1960, five people left the Koyukon Athabascan village of Nulato bound for Ruby by boat and never arrived. Among the missing was 39-year-old Harry Pitka, noted locally for his role as one of the mushers in the 1925 serum run to Nome. Traveling with him were Claude Demoski, 45; Bertha Demoski, 38; Leo Demoski, 48; and 28-year-old Emmett Nollner.

The group departed Nulato on September 25. Their boat and all five occupants vanished without a trace along the Yukon River, a waterway known for strong currents, hidden hazards, and rapidly changing weather.

The disappearance remains unsolved and has left enduring grief for the Demoski and Nollner families and the Nulato community. Did anyone in the region ever hear family stories or know more about that September 1960 trip? Please share any memories or leads that might shed light on what happened.
