2013 Map of Tyonek B-3 SW

About this map

The Theodore River carves a prominent valley through the northeastern reaches of this landscape, marking a transition from the elevated upland terrain down toward the coastal lowlands. This 2013 survey documents a remote stretch of the Matanuska-Susitna Borough where the water systems of Pretty Cr and Olson Cr weave through a network of wetlands and tundra. To the south, the Beluga River cuts across the boundary line, reflecting the dynamic hydrological environment of the Cook Inlet region. The map primarily captures a wilderness area defined by its natural drainage patterns and the absence of established road infrastructure, providing a baseline for environmental researchers and those tracking the historical boundary between the Matanuska-Susitna and Kenai Peninsula boroughs.
