Lower Tonsina sits at a significant glacial river junction where the Tonsina River flows into the massive Copper River. This 2019 survey by the U.S. Geological Survey captures a landscape defined by braided riverbeds and high-elevation terrain within the Wrangell-St. Elias National Preserve. The mapping illustrates the complex hydrology of the region, including the winding path of the Cheshnina River as it descends from the north to join the Copper.
