2016 Map of Tyonek C-4 SW

About this map

Trinity Lake and the winding course of Talachulitna Cr dominate this interior Alaskan landscape within the Matanuska-Susitna Borough. This 2016 survey captures a region defined by complex hydrology and wetland systems, where elevation contours reveal a series of low-lying ridges and basins west of the Susitna River valley. The terrain is largely unsettled, following the public land survey system through multiple townships including t17n r12w and t18n r12w. To the north, Movie Lake sits among a cluster of smaller, unnamed water bodies and marshlands that characterize this subarctic environment. The lack of established road infrastructure or named settlements on this sheet highlights the wilderness character of the area, making it a primary resource for understanding the natural drainage patterns and topographical layout of this specific section of the Alaskan bush.
