For hundreds of years, the Nimiipuu, Salish, and other Tribes follows a network of trails between the salmon-bearing Clearwater Basin and the bison-filled plains of Montana. These "trails to the buffalo" saw greater use after the Nez Perce acquired the horse in the 1700s.
This trail is part of history. In 1805, Native guides led Lewis and Clark over it. In 1877, the US military pursued the non-treaty Nez Perce over the trail during the Nez Perce War.
Because of its historic significance, the trail is part of the Lewis and Clark National Historic Trail and the Nez Perce National Historic Trail.
In the 1930s, the CCC built the Lolo Motorway roughly along the same path as the trail of old. It's use decreased significantly since the building of Highway 12. It remains a beautiful, if remote, pathway through the Clearwater.
