Arthur Floyd Ambrose, 31, was last seen September 2, 1985, in Galena, in the Yukon-Koyukuk Census Area of Alaska. He was an American Indian/Alaska Native male with black hair and brown eyes. On that day the 24-foot flat-bottomed riverboat he was on struck a bull moose on the Koyukuk River between Hughes and Allakaket and capsized. Ambrose and five others were thrown into the water and are presumed to have drowned; the other missing victims were Carol Ann Ambrose, 24; Ruth H.

Beatus, 27; Henry Beatus Jr., 26; Raymond Beatus, 24; and Robert W. Nictune, 22. None of the six were ever found. Ambrose is listed as missing with the Alaska State Troopers and in NamUs.

Is there anyone who remembers that river trip or who has information about the incident?
