The Pataha Valley and the steep canyons of the Tucannon River define this corner of the Palouse, where the border between Garfield and Columbia counties winds through a high-plateau landscape. Settlement is centered on the small communities of Turner and Covello, which sit amidst a network of hollows including Dry Hollow and Whetstone Hollow. This modern survey documents a rural environment deeply connected to its early 20th-century origins through the preservation of the Turner Cem and Covello Cem. The drainage patterns of Willow Cr and Whetstone Cr dictate the layout of the road system, which remains largely composed of rural routes like Jackson Grade Rd and Tucannon Rd. This topography reveals the persistent isolation and agrarian focus of the region, where tiny hamlets like Marengo still mark the landscape near the river's edge.
