2013 Map of Tyonek B-3 SE

About this map

Grants Cabin stands as a solitary outpost in this intricate wetland landscape within the Matanuska-Susitna Borough. The 2013 survey reveals a complex hydrological network where the Theodore River and Lewis River meander through low-lying terrain before reaching the Lewis River Slough. To the east, the Ivan River parallels these watercourses, while the Chedatna Lakes cluster in the southeastern corner, illustrating the saturated character of the Alaskan coastal plain. Human infrastructure is minimal, represented primarily by the Beluga Hwy skirting the southern boundary, which provides the only major overland access through this transition between wilderness and the Cook Inlet drainage. The map provides a detailed record of the shifting river channels and seasonal water bodies that define navigation and subsistence in this remote region.
