2020 Map of Zumwalt

About this map

The Pataha Valley and surrounding plateaus define the landscape of Garfield and Columbia Counties, centered on the historic town of Pomeroy. Settlement patterns follow the winding path of Pataha Cr, where the community of Zumwalt and the IOOF Cem sit at the edge of the valley floor. The map documents a classic agricultural layout of the Inland Northwest, with named gulches like Linville Gulch and Geiger Gulch carving through the high country. In the southwestern reaches, the Tucannon River flows past Marengo, illustrating the vital connection between these watercourses and the development of local roads like Tucannon Rd. Genealogists may find value in the specific locations of rural burials at Owsley Cem, while the road network, including the Vannaton Grade, shows how the region’s topography dictated the routes of travel between valley settlements and the high agricultural ground at Dutch Flat.
