About this map

Lewis and Clark National Wildlife Refuge dominates the northern reaches of this map, where the Columbia River breaks into a complex network of marshes, islands, and sloughs. This mid-1980s landscape shows the transition from the low-lying agricultural dikes of Brownsmead to the timbered slopes of Clatsop State Forest. The lower river environment is defined by its waterways, including the winding Blind Slough and the expansive Karlson Island, which sits across from the settlement of Knappa.

Evidence of local industry and community infrastructure is visible through features like the Big Creek Fish Hatchery and several active quarries. The rail corridor for the Burlington Northern traces the shoreline, connecting these river communities. Local family history is grounded in sites such as Prairie Cem and Maplewood Cem, while the Knappa High Sch and a Covered Bridge near Gnat Creek mark the social and geographic heart of the district.
