2017 Map of Tyonek B-8 NE

About this map

Glacial movement and riverine patterns define the landscape where the Skwentna River winds through the northern portion of this quadrangle. The map documents the shared boundary of the Matanuska-Susitna Borough and the Kenai Peninsula Borough, a line that cuts across high-elevation terrain and icy expanses. To the east, the ice-carved topography is anchored by the N Twin Glacier and S Twin Glacier, which feed the local drainage systems. In the southern half of the sheet, the Nagishlamina River flows through a deep valley, illustrating the complex watershed of this uninhabited region. The absence of roads or permanent structures emphasizes the wilderness character of the area, providing a precise record of the physical geography and administrative divisions at the time of the survey.
