The Moncravie House was a small trading establishment constructed in 1856 on the Laramie River approximately twelve miles upstream from Fort Laramie, in what is now Goshen County, Wyoming.
James Bordeaux built an independent trading post at Sarpy’s Point on the North Platte after the 1849 sale of Fort John. For two decades it served Lakota bands and Oregon Trail emigrants and stood near the outbreak of the 1854 Grattan Fight.
