2013 Map of Olsen Canyon

About this map

Seven Bays sits along the shoreline of Franklin D Roosevelt Lake, serving as a primary focal point for human activity in this portion of the Lake Roosevelt National Recreation Area. The landscape is defined by the sharp transition between the massive impoundment of the Columbia River and the deeply incised basalt drainages of the Columbia Plateau. Named canyons like Olsen Canyon, Snook Canyon, and Trinkle Canyon cut through the high ground, while more level areas like Swede Flats and Bachelor Prairie supported earlier settlement patterns. The presence of the 7 Bays Airport and the residential road network near the water contrast with the more traditional agricultural and ranching layout found further inland near Egypt. Along the southern reaches of the lake, Hawk Creek Falls marks a significant hydrological transition where Hawk Creek meets the reservoir's edge.
