About this map

Unimak Island serves as the focal point of this 2020 coastal survey, capturing the windswept and unpopulated northern reaches of the Aleutian archipelago. The map illustrates a landscape of complex topography and hydrological patterns where the Bering Sea meets the shore. The terrain is defined by low-lying wetlands and intricate drainages, including the course of Coal Oil Cr as it flows toward the sea.

As part of the Aleutian Islands chain, the region shown is primarily a wilderness landscape under federal protection. The lack of settlements or roads underscores the isolation of this portion of the Alaska Peninsula. For researchers and surveyors, the map provides precise data on the shifting contours and coastal margins of the eastern Aleutians, documenting the interface between the volcanic terrain and the sea at the start of the 2020s.
