Twin Sisters Peak dominates the northwestern corner of this 2017 survey, marking a high point in the complex terrain of the Alaska interior. The landscape is defined by the braided path of the Styx River, which flows southward through a wide valley between steep ridges. This corridor, flanked by tributary drainages like Timber Creek in the northeast, represents a significant natural passage through the wilderness. The map documents the jurisdictional divide between the Bethel Census Area and Matanuska-Susitna Borough, showing how modern administrative boundaries intersect with the ancient geographic features of the region. This 1:25,000 scale study provides a precise look at the land's contours and hydrology at the start of the twenty-first century.
