About this map

Sevenmile Lake and Eightmile Lake dominate the northern wetlands of this Matanuska-Susitna borough landscape. The terrain is defined by an intricate network of surface water and drainage systems, where the meandering course of Deep Cr cuts through the central sections while Clear Cr drains the southeastern reaches. To the west, Top Lake sits on the edge of the survey area, marking a transition in the local hydrology. The absence of established settlements or major roads highlights a wilderness character typical of the Cook Inlet region, where the primary identifiers are the township and range lines of the Public Land Survey System. These boundaries, including t21n r11w and t20n r10w, provide the essential grid for locating specific land parcels in an otherwise open and untamed Alaskan interior.
