Gareloi Island

Gareloi Island is an uninhabited volcanic island in the western Aleutian Islands of Alaska dominated by a steep stratovolcano. The island’s cliffs, lava slopes and rugged shoreline provide nesting habitat for seabirds and resting areas for pinnipeds.

The island is primarily visited by researchers and specialized wildlife tours because of its remote location and challenging sea conditions. Bird colonies and marine mammals are the principal natural attractions; terrestrial vegetation is sparse and shaped by volcanic soils and maritime climate.

The island is of volcanic origin and has experienced historic eruptive activity that created its present topography. Human use has been limited to intermittent scientific visits and monitoring of volcanic and ecological conditions.

Gareloi lies in the Bering Sea portion of the Aleutian chain in western Alaska and is part of the Aleutian archipelago. Access is by boat or research vessel from larger Aleutian bases and it is remote from inhabited centers.

• Conservation status: The island is uninhabited and is administered as part of the Aleutian Islands unit of Alaska's maritime conservation areas.
• Wildlife interest: Noted for dense seabird colonies and haul-outs of marine mammals, making it of interest to researchers and wildlife observers when accessible by boat.
