About this map

Pataha Creek and the Tucannon River define the topography of this corner of Southeast Washington, where steep-walled gulches give way to high plateau country. The community of Pomeroy sits at the northeastern edge of the sheet along Pataha Creek, serving as a gateway to the fertile Pataha Valley. Moving southwest, the landscape is punctuated by the small settlements of Zumwalt and Marengo, the latter situated near the confluence of local drainages.

Genealogists will find the locations of the Owsley Cem and Cox Cem particularly valuable for tracing early families in Garfield and Columbia counties. The region's agricultural and transit roots are evidenced by a network of local routes such as Vannaton Grade, Marengo Rd, and Bartels Rd, which navigate the complex terrain of Tatman Gulch and Dutch Flat. The boundary between Garfield Co and Columbia Co bisects the southwestern portion of the map, following the ridgelines above the river valleys.
