Umiaks were made from drift wood and walrus skins. The walrus skins were traded with Little Diomeders. The Little Diomeders would migrate each spring from Little Diomede Island to Kotzebue and would stay in Shishmaref for a week or two before moving on to Kotzebue. They would return by the North Star freighter (68-71) back to Little Diomede on its south bound trip. Villagers traded black meat and seal oil for walrus skins from them. Now everyone has wooden speed boats which are made by the locals.
