2014 Map of Grand Ronde

About this map

The tribal and civic hub of Grand Ronde Agency serves as the focal point for this 2014 study of the northern Oregon Coast Range foothills. Situated at the convergence of the South Yamhill River and Rogue River, the landscape transitions from the agricultural valley floor at Valley Junction to the prominent heights of Spirit Mtn and Mule Tail Ridge. This area, divided by the Yamhill Co Polk Co line, shows a complex network of forest and ranch roads such as Tindle Creek Rd and SW Agency Creek Rd that navigate the ridges and narrow creek drainages. Local heritage is preserved in sites like the Holmes Cem and Hussey Cem, while modern infrastructure including the Mendenhall Airstrip and the Mountain Springs Ranch Reservoir highlights the continued utility of the land for ranching and transport.
