Hudson's Bay Co. post on left bank of Athabaska river at confluence of Red river (now called McKay river since 1912) and the Athabaska. This fort is now called Fort McKay. It was probably constructed about 1870 and appears on the list of 1872 for first time. It probably superseded the older post Pierre-au-Calumet situated about 10 miles farther north. Shown on map No. 11 and Red River on map No. 34. See Pierre-au-Calumet.
