About this map

The Tualatin Valley floor is dominated by the sprawling urban footprint of Hillsboro, stretching from the industrial centers near Portland-Hillsboro Airport south to the wetlands of Jackson Bottom. This modern landscape preserves the names of its agricultural and early industrial past, including the planned company town of Orenco and the small communities of Reedville and Witch Hazel along the southern rail corridor.

Upland from the valley floor, the terrain rises into the Tualatin Mountains and Pumpkin Ridge, where smaller settlements like Helvetia and West Union maintain a more rural character. Genealogists will find significant value in the mapped locations of Old Scotch Cem and Helvetia Cem, while the course of the Oregon Electric RR serves as a reminder of the interurban rail network that once defined local transport. Numerous small reservoirs, such as Bastion Reservoir and Hembree Reservoir, dot the foothills, reflecting the region's managed water systems.
