Originally a North West Co. post on South Branch of Saskatchewan river at mouth of Red Deer river, on north bank. Built 1791. It was abandoned 1804 and rebuilt in 1805 by John McDonald of the North West Co. and then called New Chesterfield House. In 1822, after the coalition of the two companies, the Hudson's Bay Co took over the North West Co. establishment and opened Chesterfield House under Donald McKenzie. It was abandoned after a few years on account of Indian troubles. It is shown on Arrowsmith maps 1832 (No. 101), 1850 (No. 100), 1854 (No. 77) and 1857 (No. 8) and is included in Company lists of 1857, but not later. The X.Y. Co. also had a small post in the immediate neighborhood.
