Unalga Island dominates the northern portion of this maritime survey, situated where the Bering Sea meets the North Pacific Ocean. This remote archipelago landscape is defined by its isolation and the naming of small landmasses such as the Baby Islands, which include features with Unangan (Aleut) labels like Tan'gaagamax, Ixsaxsxin, and Tan'gan. The cartography documents the transition between the Aleutians East Borough and Aleutians West Census Area, marked by a boundary line crossing the open water. Navigational channels like Baby Pass and Akutan Pass suggest the maritime movement required to traverse these island chains. The map provides a look at the topographical contours of these uninhabited landforms, preserving indigenous place names like Qyanan and Qusilxtax alongside broader maritime descriptors.
