- Mill Creek is a 36.5-mile-long (58.7 km) tributary of the Walla Walla River, flowing through southeast Washington and northeast Oregon in the United States. It drains from the western side of the Blue Mountains into the Walla Walla Valley and flows through the city of Walla Walla, which draws most of its water supply from the creek. The creek is named for the sawmill built in 1845 by Marcus Whitman, one of the first European settlers in the valley.
- Nez Perce National Historical Park (Wikipedia)
The Nez Perce National Historical Park is a United States National Historical Park comprising 38 sites located across the states of Idaho, Montana, Oregon, and Washington, which include traditional aboriginal lands of the Nez Perce people. The sites are strongly associated with the resistance of Chief Joseph and his band, who in June 1877 migrated from Oregon in an attempt to reach freedom in Canada and avoid being forced on to a reservation. They were pursued by U.S. Army cavalry forces and fought numerous skirmishes against them during the so-called Nez Perce War, which eventually ended with Chief Joseph’s surrender in the Montana Territory.
