2016 Map of Tyonek B-1 NW

About this map

The Little Susitna River meanders through the eastern portion of this quadrangle, forming complex oxbows and channels that define the local hydrology. This 2016 survey, produced by the U.S. Geological Survey, reflects the wetland-dominated landscape typical of the Matanuska-Susitna region. In the western reaches, the drainage of McGuire Creek and Fish Creek further shapes the terrain. The map is largely defined by its natural water features and extensive marshlands, showing very little in the way of human infrastructure or road networks. The intricate survey of these water bodies highlights the shifting nature of the river systems in this part of Alaska, providing a detailed look at the drainage patterns before potential future development or environmental change.
