Innoko National Wildlife Refuge dominates the central and northern sections of this Alaskan landscape, protecting a significant portion of the Yukon-Koyukuk interior. The terrain is characterized by complex contouring that defines the drainage basin of Sucker Cr, which winds through the southeastern quadrant of the survey. As an uninhabited wilderness area, the map provides a precise layout of the township and range system, specifically marking t26s r4w, t26s r3w, t27s r4w, and t27s r3w. These survey lines emphasize the administrative division of this roadless region within the Unalakleet A-1 NW quadrangle, where the natural hydrography and elevation data are the primary indicators of the land's character.
