In 1880, the government built Fort Spokane at what is now Lake Roosevelt National Recreation Area in Washington state. The fort was constructed to keep the peace between settlers and the Colville and Spokane Indian tribes and ultimately went through three phases before being abandoned and then coming under the management of the National Park Service: military base, Indian boarding school, tuberculosis hospital.

Here's a throwback to circa 1905 or thereabout. Before becoming Lake Roosevelt National Recreation Area, there was a military fort. According to the National Park Service, "Fort Spokane and the surrounding landscape hold great historic significance. For thousands of years, the area was a gathering place for native tribes fishing the rapids of the Spokane River. In 1880, the U.S. Army established a fort above the confluence of the Spokane and Columbia Rivers. In 1898, the military fort was closed. The buildings were then used as an Indian boarding school and tuberculosis hospital.
