Mt Ingalls and Smith Peak dominate the high-elevation terrain of the Plumas National Forest in this mid-2010s survey. The landscape is defined by the significant watershed of Lake Davis, where Big Grizzly Cr and Cow Cr feed into the northern coves and points, including Lightning Tree Point and Dan Blough Cove. The area maintains a network of forest access routes and specialized spurs, such as the Tramway Spur, Grizzly Loop, and Happy Valley Spur A, reflecting the region's history of timber management and recreation. Small named junctions and localities like Gate Place, Four Corners, and Five Corners serve as landmarks within the valleys. The topography transitions from the high eastern reach of Grizzly Ridge down into the meadows of Grizzly Valley and Threemile Valley, preserving the spatial layout of this Sierra Nevada backcountry during a period of modern forest service administration.
