Hudson's Bay Co. fort on Lake Athabaska on Coal island, one mile from Fort Chipewyan. In 1808 the Hudson's Bay Co. abandoned the whole of the Athabaska district to the North West Co. and also Fort Nottingham built in 1802. In 1815 they returned and built Fort Wedderburne. This fort was seized by Norman McLeod of the North West Co. March 23, 1817, but was re-established in 1818. In 1820, Simpson, afterwards Governor, wintered there. After the union of 1821, the Hudson's Bay Co. took over fort Chipewyan, (which had been enlarged several times), and after about 1860 fort Wedderburne was closed. Maps No. 100, 101 & 8.
