2023 Map of Lewis Creek

About this map

The South Fork John Day Wild and Scenic River carves through this remote stretch of Grant County, where the high-elevation landscape is defined by the transitions between the Malheur National Forest and private ranching interests. This 2023 survey documents a network of water sources vital to the region's cattle-grazing history, including Sulphur Spring, Wickiser Spring, and Officer Spring. The rugged relief is punctuated by landmarks such as Buck Mtn and Blackhorse Butte, while the drainage system of Venator Creek and Rosebud Creek feeds the larger river basin. Human activity is marked by the presence of the Inshallah International Airport and the historical access provided by the Izee Road to Izee Ranch, which connects isolated homesteads and pastures across the high desert terrain.
