Petes Mountain rises prominently above the confluence of the Willamette River and the Molalla River, anchoring a landscape defined by its waterways and early transport routes. In this era, the riverbank settlements of Pulp, Coalca, and New Era are clearly delineated along the Southern Pacific railroad line, reflecting the industrial and transit-oriented character of the river corridor. To the south, the expansive French Prairie transition begins, where the Pudding River winds through agricultural lands.
