About this map

The Little Susitna River winds through a complex landscape of glacial deposits and wetlands in this 1970s orthophotomap of the Matanuska-Susitna region. The dominant geological feature is the Elmendorf Moraine, which shapes the distribution of numerous water bodies like Diamond Lake, Yohn Lake, and Carpenter Lake. This specific map format utilizes an orthophotomosaic to show actual vegetation patterns and terrain textures alongside traditional topographic data, revealing a territory primarily defined by its natural hydrology and limited human infrastructure.

Evidence of remote access and early industry appears in the form of a Landing Strip, a Jeep Trail, and a Gravel Pit. Historical transit patterns are marked by the Winter Crossing over the river, while several Drill Holes suggest subsurface exploration during this era. Other smaller named lakes, including Jewell Lake, Cann Lake, Middle Lake, and My Lake, are scattered across the moraine and lowland flats, providing a detailed look at the drainage patterns of the area before modern development.
