Seven Dikes Mtn dominates this interior landscape within the Yukon-Koyukuk Census Area, serving as a prominent topographic anchor for the surrounding watershed. The drainage patterns are defined by the northern flow of Joanna Cr and the more central Patricia Cr, which carve through the high-elevation terrain. This 2018 survey documents the remote wilderness character of the region, illustrating a landscape defined by sharp vertical relief rather than human settlement. The map clearly delineates the township and range boundaries of t35n r20e and t35n r21e, providing a precise look at the Public Land Survey System grid as it applies to this section of the Alaskan interior.
