Seymour Tuzroyluke, Jr., was 33 when he was last seen on December 4, 1989, in Kotzebue. He was traveling along the Chukchi Sea coast from Kivalina toward Point Hope on a black Yamaha snow machine and did not arrive at his destination or make contact afterward. He was dressed in a white parka, grey and green overalls, and red mukluks, and was carrying a blue bag with survival gear.

Seymour is an American Indian/Alaska Native male, 5 feet 6 inches tall, about 170 pounds, with black hair, brown eyes, and scars on his upper right arm and buttock. The Alaska State Troopers have an open investigation; the case was entered into NamUs in March 2020 and the official record lists environmental factors as the likely circumstances of his disappearance.

Does anyone who lived or traveled between Kivalina and Point Hope in December 1989 remember seeing Seymour or his snow machine?
