(1845, 1848 – 1855) For the latter years of its operation, this fur trading post was operated by the HBC's Antoine Desjarlais. The exact location of the post is unknown, though it may have replaced Lena House on the slope of Turtle Mountain.
- Lena House
- (1801 - 1802) Lena House is only one of the only fur trading posts established on Turtle Mountains. The HBC established this post with the goal of shutting down all other forts in the area.
- The Souris River Fur Trade
- The Fur Trade on the Souris River flourished because of the proximity of grassland favoured by grazing bison. Pemmican made from these magestic beasts supported the rest of the fur trade.
