It was built in the early part of 1837 near
Platteville, Colorado at a cost of $12,000 by
Peter A. Sarpy and
Henry Fraeb and partially financed by the Western Division of the
American Fur Company. This fort was very aggressive and attempted to capture trade in the
Rocky Mountains. Sarpy said that "My object is to do all harm possible to the opposition and yet without harming ourselves." To meet the local competitive pressure, Sarpy and Fraeb financed good for their post, financed by Pratte, Chouteau & Company of St. Louis. They also took in buffalo robes worth $9,715.87 ($249,125 today), but their business interest was transferred in October 1838 to Bent, St. Vrain & Company, which operated Fort Saint Vrain. The post was demolished after the inventory was removed. ==See also==
