Roald Amundsen travelled the west coast by sled in 1904, and Henry Larsen wintered at Pasley Bay on his successful voyage through the Northwest Passage (1940-42), journeying all around the peninsula by sledge. There is only one community on the peninsula, the hamlet of Taloyoak, which lies on the isthmus.
