2023 Map of Anchorage B-4 NE

About this map

The Glacier Fork Knik River carves a deep path through this corner of the Southcentral Alaskan wilderness, where the southern reaches of the Grasshopper Valley meet rising alpine terrain. This 2023 map captures a high-elevation landscape defined by the intersection of the Matanuska-Susitna Borough and the Chugach Census Area. The absence of developed roads or permanent settlements underscores the primitive state of this glacial drainage system, which remains dominated by natural watercourses and the high-relief contours of the surrounding mountains. Surveyed under the modern US Topo standard, the sheet provides a precise accounting of contemporary hydrology and land boundaries in a region where the braided river channels are subject to seasonal shifts from glacial melt.
