Hillsboro serves as a central hub, while the Oregon Electric Railways and Southern Pacific lines weave through the landscape, connecting small farming communities like Orenco and Quatama. To the east, the Willamette River and Columbia River converge near St Johns and Linnton, highlighting the industrial and maritime character of the riverfront with landmarks such as the Post Office Bar and the Gasco plant.
