About this map

Gulf of Alaska coastal dynamics are captured in high detail here, showing the intricate network of silt and water where the Glacier River and Eyak River meet the sea. The landscape is dominated by shifting bars of sand and vast stretches of mud, with the Egg Islands standing as prominent landmarks within the Egg Island Channel. The influence of glacial runoff is evident in the complex braiding of Government Slough and Glacier Slough, which carve through the tidal flats.

Fringing the northern edge, the rugged terrain of the Chugach National Forest rises abruptly from the water, marked by the Eyak Trail and the cascades at Crystal Falls. This area, documented just after the mid-century, illustrates a wild shoreline defined by tidal reach and river discharge. The map provides an essential record of these coastal features near Hartney Bay before further natural shifts and modern development altered the drainage patterns.
