The Clark Fork river cuts through the northern portion of this landscape, carving a path between the Lolo National Forest and the peaks of the Sapphire Mountains. This area, situated along the border of Missoula Co and Granite Co, centers on the settlement of Ravenna, where the river valley provides a natural corridor for transport. The terrain is defined by a series of prominent gulches and high-elevation landmarks such as Beavertail Hill and Burnt Mtn. A network of forest roads and trails, including Bonita Station Rd and the Tyler Creek Trl, illustrates the modern access into the steep backcountry. The map also highlights significant topographical features like the Whitetail Saddle and Welch-Gillespie Saddle, which represent historical crossing points through the high ridges. Modern water sources are frequent, with named springs like Mormon Spring and Lodgepole Spring dotting the drainages.
