Thoroughfare Creek and Portage Creek drain the steep topography of this wilderness area in the Matanuska-Susitna Borough. These watercourses flow through high-elevation drainage basins, where the 2023 survey data illustrates a landscape defined by significant elevation changes and seasonal wetlands. Devil Creek emerges in the southeastern portion of the map, illustrating the network of glacial and mountain runoff that characterizes this region of the Talkeetna Mountains. The grid of the Public Land Survey System, including boundaries for t22s r9w and t33n r1e, provides a spatial framework for understanding land management in this undeveloped terrain before modern infrastructure reaches these remote drainages.
