2023 Map of Valdez A-4 NW

About this map

The Tsina River flows through this rugged corridor of the Chugach Mountains, providing a natural pathway for critical infrastructure. Modern engineering is heavily represented here, as the Alaska Pipeline and the Richardson Highway parallel the river's course through the mountain passes. The map highlights the sharp relief between the river valleys and high peaks such as Mt Dimond in the northwest corner. This area serves as a primary transit link between the interior and the coast, crossing the boundary between the Copper River Census Area and Chugach Census Area. Further south, the terrain transitions toward the headwaters of the Lowe River, illustrating the complex drainage patterns of the Alaskan wilderness.
