The Hartman River flows through this corner of the Alaska wilderness, carved into the landscape of the Bethel Census Area. This terrain is characterized by high-altitude drainage systems and steep contour gradients, where the waters of Boulder Cr navigate the northern reaches of the quadrangle. The map documents the vast, uninhabited Public Land Survey System divisions, specifically marking the transition between townships t21n r23w and t22n r23w. The survey provides a technical look at the hydrology of the upper river valleys before they descend into the larger Alaskan river basins.
