About this map

Lake Umatilla dominates the center of this survey, marking the state boundary between Oregon and Washington where the Columbia River carves through the landscape. The northern shore in Klickitat County rises steeply toward Alder Ridge, while the southern bank in Gilliam County transitions into the broad expanse of Hurlburt Flats. These contrasting elevations reveal a geography shaped by the river's path, with small settlements like Sixprong and McCredie situated along the northern drainages and Moona positioned near the water's edge.

Infrastructure in this area follows the natural contours of the river valley, with several named routes such as Frontage Rd and Willow Creek Rd facilitating travel through the terrain. Numerous waterways, including Sixprong Creek, Pine Creek, and Willow Creek, feed into the Columbia system. The presence of Willow Lake near the confluence of the creek and river provides a distinct landmark for researchers tracing the historical development of these shoreline communities and their relationship to the managed waters of the basin.
