Iñupiat Ada Blackjack Johnson was part of an expedition that attempted to claim the island of Wrangel on behalf of Canada and Great Britain. The conditions for the expedition were difficult. Rations ran out and the team was unable to find enough game on the island to survive. One member died on the island and three others disappeared after attempting to go for help. Ada survived as was rescued in August of 1923. Interestingly Ada did not profit from the many books published about the expedition. Niven, Jennifer.
