2020 Map of Deer Island

About this map

The Columbia River serves as the dominant geographic feature of this 2020 map, separating Oregon and Washington along a complex system of islands and sloughs. On the Oregon bank, the community of Columbia City and the historic settlement of Deer Island are connected by the lowlands of the Columbia City Channel and Multnomah Channel. This riverine landscape is dotted with numerous inland water bodies like Swan Lake, Thorn Lake, and Horsepasture Lake, which reflect the hydrology of the floodplain. Local history is anchored by the Kinder Cem and Masonic Cem, while the BNSF Railway tracks follow the Washington shoreline through Kalama and Woodland. The elevation rises sharply to the east at Green Mountain and Martin Bluff, offering a contrast to the marshy flats of Goat Island and Burke Island that define the central river corridor.
