2017 Map of Tyonek A-8 NE

About this map

Ch'akajabena Lake dominates the central portion of this Kenai Peninsula region, serving as a significant glacial catchment fed by the high-elevation meltwater of the Shamrock Glacier. The map illustrates a dramatic Alaskan transition from the ice-carved heights of the glacier down to the Shamrock Lake basin and the Chilligan River corridor. This 2017 survey details a landscape defined by sharp topographic relief and massive hydrological systems, where the absence of roads or permanent settlements highlights the wilderness character of the western Kenai Peninsula Borough. The drainage patterns from the glacier through the lakes and into the river systems provide clear evidence of the active geological forces shaping this remote portion of the Tyonek quadrangle.
