1921 Map of Corvallis

About this map

Corvallis and the Oregon Agricultural College anchor this partial 1921 survey, which depicts the development of the Willamette Valley before the full quadrangle was completed. The landscape is defined by the winding courses of the Marys River and Muddy Creek, leading toward the Boonesville Channel and Kiger Island in the east. This early twentieth-century snapshot shows a rural economy supported by the Southern Pacific railroad, connecting smaller communities like Philomath, Avery, and Pheasant.
