In the early 19th century, various
fur trapping companies set up posts along the front range of the Rocky
Mountains in what is now Colorado: Bent and St. Vrain (Fort Lookout), Sublette
and Vasquez, Fort Jackson, and Fort Lupton. These “forts” were built in the
1830s within 10 miles of the South Platte River” forming a chain connecting the
fur traders.
Trappers based at these forts and working for
larger companies went out into the wilderness to trap beaver and buffalo or to
trade with the various native tribes living in the area including the Arapahoe,
Cheyenne, and occasionally the Crows, Pawnees, Shoshones and Blackfeet. Many of the pelts collected
by the trappers, either through trapping or trade, would be collected or sent
back east for sale.
It is difficult to track the movements of the
trappers as there is little written evidence of their travels, but a few were
known to have traveled along the South Platte River and likely through the Fort
Morgan area.
