2023 Map of Rye Grass Coulee

About this map

Juniper Dunes Wilderness occupies the southeast corner of this modern Franklin County landscape, marking a significant protected environment within the interior Columbia Basin. The terrain is defined by the deep incisions of Smith Canyon and the winding namesake Rye Grass Coulee, which cut through the high plateau. The network of local roads reflects the rural and agricultural character of the region, including names such as Samual Brown Trail Rd, Bengen Ln, and Hummel Ln. These named routes, along with Blackman Ridge Rd and Rye Grass Coulee Rd, provide essential access across the varied elevations of the coulee country, illustrating how modern transportation follows the natural contours of this semi-arid Washington environment.
