East Fork Susitna River and Boulder Creek define the drainage patterns of this high-elevation interior landscape in the eastern Matanuska-Susitna region. The terrain is characterized by steep contour gradients and high-alpine glacial valleys, with watercourses cutting through massive geological formations. Mapping here relies on precise data from the U.S. Department of the Interior and the U.S. Geological Survey to document a region where human infrastructure is largely absent in favor of raw natural hydrology. The elevation data reveals the stark relief of the Alaskan wilderness, providing an essential record for those studying the physical geography of the Susitna River's upper reaches.
