In 1846–47 he explored the Gulf of Boothia northwest of Hudson Bay. In 1848–51 he explored the Arctic coast near Victoria Island. In 1854 he went from Boothia to the Arctic coast and learned the fate of Franklin. He was noted for physical stamina, skill at hunting and boat handling, use of native methods and the ability to travel long distances with little equipment while living off the land. Pic.
