What did Ipilkvik and tukkolerktuk explore?

The two Inuit (Ipilvik and Tukkolerktuk) went with Hall to the the United States where they helped him on his lecture tour which raised money for further exploration. Then they returned with Hall, and were landed by a whaling ship on the northern coast in 1864. For five years they performed heroic services for Hall. It was on a trek from Pelly Bay area down the coast of Keewatin that Hall was able to collect facts and relics of the ill-fated Franklin expedition of 1846.
