2023 Map of Valdez B-5 SW
USGS Topo · Published 2023About this map
Tonsina Glacier dominates the central portion of this 2023 survey in the Copper River Census Area, serving as the massive source for the north-flowing Tonsina River. The landscape is defined by extreme elevation changes and drainage patterns that feed into the Tsina River in the southern reaches of the quadrangle. As a modern topographic study, it provides an exact record of glacial extent and watercourse positions within the Chugach Mountains. The absence of roads or established settlements emphasizes the remote nature of this glacial corridor, where surveyors focused on the complex interaction between ice fields and the high alpine river systems that emerge from them.
