Explorer's house at the extreme eastern end of Great Slave lake. Built by McLeod of the Hudson's Bay Co. for Captain Back in 1833, at mouth of Lockhart river. Now in ruins. It was operated as a fur trading post for some years by the Company. Tyrrell in 1901 described the ruined fort as having been beautifully situated on a green terrace 20 feet above the harbour and 200 feet from the shore. The country was thinly wooded with young spruce. The fort, which had been burned, was 30 by 50 feet with three chimneys and five open fireplaces, five rooms with fireplace in each. There were 2 smaller buildings 18 feet square. Only the stone chimneys now remain.
