1934 Map of The Dalles

South of the river, the terrain rises toward the Mt Hood National Forest, where the Twin Pines Lookout stands watch over the drainages of Mill Creek and Fifteenmile Creek. The map shows several smaller settlements and sidings like Mosler, Rowena, and Ortley along the river cliffs, while the presence of the Willamette Base Line provides the primary surveying anchor for the entire region. The north bank remains largely indicated as a preliminary unsurveyed area, emphasizing the river as a stark boundary between the established townships of Wasco County and the Washington side.
