Sheenjek River winds through this expanse of the Yukon-Koyukuk Census Area, defining the drainage patterns of a landscape characterized by significant elevation changes. In the northwest corner, the terrain rises toward the summit of Helmet Mtn, a prominent landmark that overlooks the river valley below. The map illustrates the wilderness as it was documented in 2018, showing the braided channels of the river as it flows southward through townships like t33n r16e and t32n r16e. This sheet is dominated by natural contours rather than human infrastructure, serving as a primary record of the topography and hydrology in this remote portion of northern Alaska.
