The vast wetland interior of Alaska’s T25n R11e and T24n R12e townships is defined by an intricate network of lakes, ponds, and drainage patterns. This 2018 survey highlights the complex hydrography of the Yukon-Koyukuk region, where subtle elevation changes dictate the flow of water across a landscape dominated by marsh and riparian zones. The lack of named settlements or roads reflects the remote character of this terrain, where the Public Land Survey System grids, such as T25n R12e and T24n R13e, serve as the primary markers for navigation and land management. Researchers studying Alaskan hydrology will find this a detailed record of water distribution and land cover in the late 2010s.
