Lewis River meanders across this pre-war landscape, connecting the high waters of Lake Merwin in the northeast to the settlements of Woodland and La Center. The area is defined by a network of small agricultural and timber communities, including Battleground, Ridgefield, and Cherry Grove. The 91st Observation Squadron provided aerial photography for this 1939-1940 study, capturing the early alignment of the Pacific Highway and localized infrastructure like the State Fish Hatchery near Etna.
