Sawtooth Ridge dominates this landscape along the eastern edge of the Lewis & Clark National Forest, where the mountain front meets the plains. The hydrological engineering of the early twentieth century is clearly visible in the path of the Pishkun Canal and the Willow Cr Feeder Canal, which divert water from the Sun River and Diversion Lake to support regional agriculture. The map detail highlights a rugged terrain marked by numerous named gulches and flats, including Hannan Gulch, Norwegian Gulch, and Agropyron Flats. These geographic markers, along with landmarks like Sugar Loaf and Roost Hill, provide critical reference points for understanding the historic land use and surveying of this Teton and Lewis and Clark county border region.
