About this map

Yistletaw sits along the northern banks of the Yukon River, serving as a focal point in a landscape defined by an intricate network of waterways and islands. This mid-century survey captures the region's historical connectivity through the Abandoned Telegraph Line, which once served as a vital communication link across the Alaskan interior. The terrain is dominated by prominent landmarks such as Bishop Rock and Pilot Mountain, while the river itself is fragmented into numerous channels and sloughs.

The hydrology of the area is exceptionally complex, featuring major diversions like Nikolai Slough and Pilot Mountain Slough. These secondary channels create large landforms including Bishop Rock Island and Whontleya Island. The presence of smaller islands like Cat Island, Hen Island, and Cook Island further illustrates the shifting, braided nature of the river system during the 1950s, providing a detailed record of the geography before contemporary environmental changes.
