2017 Map of Tyonek B-5 NW
USGS Topo · Published 2017About this map
Triumvirate Glacier dominates the central landscape of this wilderness region, marking the slow geological transition of the Alaskan sub-arctic. This 2017 survey documents the precise boundary line between the Matanuska-Susitna Borough and the Kenai Peninsula Borough, which bisects the quadrangle horizontally. The ice field's edge sits adjacent to Strandline Lake, a significant water body formed by the glacial margins in the northwestern sector. Further north, the headwaters of W Fork Coal Cr drain the high country, illustrating the hydraulic patterns of the Cook Inlet watershed. This map provides a technical baseline for tracking glacial retreat and drainage shifts in an area defined by its massive ice features and topographical relief.
