On September 25, 1960, 28-year-old Emmett Nollner and four companions — Claude Demoski, Bertha Demoski, Leo Demoski, and Harry Pitka — left the Yukon River village of Nulato by boat bound for Ruby and were never seen again. Their failure to arrive in Ruby prompted a report to the Alaska State Troopers on September 26, 1960, and searches were conducted but turned up no wreckage, belongings, or human remains.

With no survivors and no recovered evidence, the specific circumstances that led to the disappearance remain unknown.

Does anyone have family knowledge, local memories, or information about river travel on that stretch of the Yukon in 1960 that could shed light on what happened?
