This map shows the site of the trading post at Fort Lookout.
Fort Lookout sat on the west bank of the Missouri River a few miles below a well-known and heavily-utilized ford. For centuries, the ford had enabled mammalian herds and Native Americans to cross the wide river.
The site of the fort enabled European-American hunters based there to easily access the wildlife moving across the Upper Missouri territory’s mammalian road network. The fort also facilitated the fur trade with the Native Americans traveling along those same roads.
Old maps, in conjunction with other primary sources, make it possible to recreate the ancient mammalian road network that once crisscrossed the northern Great Plains region of North America. Such information can assist wildlife biologists and government agencies working to restore mammalian populations.
