About this map

The East Fork Yentna River dominates this portion of the Susitna Valley, where the river's braided channels and wide gravel bars illustrate the dynamic nature of glacial runoff in the Alaska Range foothills. The landscape is a complex network of wetlands and minor tributaries, including the West Fork Yentna River and Fourth of July Creek. A significant portion of the eastern territory is protected within the Denali National Preserve, maintaining a wilderness character largely untouched by permanent road infrastructure. Higher elevations are marked by seasonal drainages such as Fish Creek and Rich Creek, which feed into the primary river systems. Scattered water bodies like the Midway Lakes provide critical habitat amidst the shifting river plains, offering a detailed look at the hydrology of the Matanuska-Susitna region.
