1975 Map of Salem West

About this map

The urban sprawl and industrial development of Salem are captured in high detail on this 1975 orthophotomap. The imagery, prepared in cooperation with the Soil Conservation Service, reveals the intricate relationship between the city's built environment and the sinuous path of the Willamette River as it flows through the valley. While much of the eastern portion of the sheet is dominated by the dense street grids of the state capital, the southern reaches show the emerging residential patterns around Liberty. The transition from urban center to organized agricultural fields and woodlots is clearly visible, providing researchers with a precise visual record of land use and development during the mid-1970s. This specific survey serves as a vital bridge for understanding the transition of the Marion County landscape before the further expansions of the late 20th century.
