2023 Map of Gulkana A-4 SW

About this map

Glennallen and the surrounding Copper River basin are defined by the powerful course of the Tazlina River, which carves through the landscape in this modern US Topo survey. The Glenn Highway serves as the primary artery connecting the region, passing through Tolsona and leading toward the essential highway junction at Glennallen. The terrain is characterized by a complex network of wetlands and small water bodies, including Plumb Bob Lake, Mud Lake, and the curiously named Salt Spring. High-gradient drainage from tributaries like Nickel Creek and Durham Creek flows toward the glacial river system, illustrating the hydrology that governs travel and settlement patterns in this part of Alaska. This map provides an exceptionally clear view of the interface between established transport corridors and the persistent natural watercourses of the interior.
