2020 Map of Coulee City

About this map

Coulee City sits at the northern edge of this high-desert landscape where the Grand Coulee widens into a complex network of ancient flood-carved geology. The 2020 geography highlights the critical role of water management in this arid region, featuring the southern extent of Banks Lake and the Main Canal which feeds the Columbia Basin Project. To the south and west, the dramatic terrain of the Sun Lakes-Dry Falls area is revealed, including the towering Umatilla Rock and the dry precipice of Dry Falls. Historical paths like the Caribou Trail and Monument Coulee Trail suggest the long-standing importance of this corridor for passage through the basalt coulees. Small railroad-related settlements and sidings like Odair and Bacon flank the town, connected by the infrastructure of the Bacon Tunnel and rural routes traversing Arbuckle Flats.
