On the way west, on May 8, 1805, Lewis named the Milk River for its cloudy appearance. He hoped this river would connect with the Saskatchewan River so that America could take over some of the fur trade dominated by the Canadians.

As a result, the expedition found rivers where they expected none and puzzled over which routes to follow.
