The Tyone River meanders across this subarctic landscape in the Matanuska-Susitna Borough, defining the primary drainage for a region characterized by extensive wetlands and glacial terrain. This 2023 survey documents the modern hydrography of the Alaskan interior, where the river's path is the most prominent named landmark amidst a network of unnamed lakes and high-elevation contours. The map's grid layout, defined by the Public Land Survey System boundaries such as t11n r9w and t10n r9w, underscores the remote and largely uninhabited character of this portion of the Gulkana C-6 NW quadrangle. For those studying the hydrology of the Susitna River basin, this record provides the exact contemporary alignment of the upper Tyone waterway.
