"The City of Phoenix, Oregon was one of the earliest pioneer settlements in Southern Oregon. Many vestiges of its rich past are still visible today. The impressive Colver House, on Highway 99 at the south end of town, was built in 1855 by one of the first settlers Samuel Colver.
Colver came west from Ohio in 1850, taking up a donation land claim of 640 acres on a site where Phoenix now stands. The town site of Phoenix was laid out on property he donated to the city in 1854.

Back in the 1850's Phoenix was the hub of the Rogue Valley. The Rogue River and Modoc Indian Wars, the Northwest gold rush, and the onset of the Civil War all played a part in the growth of this frontier town." -phoenixoregon.net
