2023 Map of Tyonek D-1 NW

About this map

Trapper Lake and the winding course of the Deshka River anchor this Alaskan landscape within the Matanuska-Susitna Borough. This high-resolution 2023 survey documents a complex network of wetlands and seasonal waterways, including the drainage of Trapper Creek as it flows south toward the Susitna Valley. The terrain is characterized by the Kashwitna Knobs in the southeastern corner, providing a rare point of elevation in an otherwise low-lying, water-saturated basin. This map serves as a vital record of the modern hydrography in a region where the shifting channels of the Deshka River define the local topography and access. The absence of developed roads or settlements on this sheet highlights the primitive state of the wilderness in this part of the Tyonek D-1 NW quadrangle.
