Donnelly and Roseberry anchor this portion of Long Valley in central Idaho, where the landscape is defined by the expansive waters of Lake Cascade. The eastern edge of the map rises into the Payette National Forest, a stark contrast to the low-lying agricultural and residential lands to the west. This area features a complex irrigation network essential to the local valley economy, including the Gold Fork Canal, East Fork Roseberry Ditch, and Center Canal.
