About this map

Chistochina River defines the eastern portion of this glacial-fed landscape, where the braiding water patterns indicate the dynamic nature of this northern interior river system. The terrain is dominated by the Sinona Creek watershed, which drains southward through a series of complex elevation contours before joining the main river valley. Near the center of the sheet, Sinona Lake sits as a significant alpine water body, likely a remnant of geological processes that shaped this portion of the Copper River Census Area. The lack of established road infrastructure or named settlements emphasizes the character of this region as a managed wilderness area, where natural drainages like the Middle Fork Chistochina River serve as the primary landmarks for navigation and land study. This survey provides a precise modern baseline for understanding the hydrologic features and topography of the high-latitude drainage basin.
