2020 Map of False Pass D-5 NW

About this map

Unimak Island serves as the focal point for this survey of the eastern Aleutian Islands, revealing a landscape defined by dramatic elevation changes. The northern half of the sheet is characterized by lower coastal terrain dotted with numerous small lakes and ponds, while the southern portion rises sharply into high ridges. The absence of roads or established settlements on this map underscores the isolation of this part of the Aleutians East Borough, where the environment remains shaped by natural processes rather than human development. Surveyors from the U.S. Geological Survey have captured a moment of relative stillness in this maritime region, utilizing National Elevation Dataset contours from 2019 to delineate the steep slopes of the southern island interior.
