Tl’oo Hanshyah Mtn dominates this portion of the Yukon-Koyukuk Census Area, rising prominently from the surrounding interior Alaskan landscape. This 2018 survey documents a region of dramatic elevation changes and sparse human development, characterized primarily by its complex topography and the underlying Public Land Survey System grid. The map covers the intersection of several townships, including t23n r24e and t23n r25e, providing a precise record of the land divisions and natural terrain near the Black River. The absence of roads or established settlements on the sheet underscores the remote character of this high-latitude terrain, where the mountain peak serves as the primary geographical anchor for the surrounding wilderness.
