2019 Map of Sutwik Island B-6 NE

About this map

Unavikshak Island anchors the northern edge of this coastal survey, rising from the waters of the Pacific Ocean within the Lake and Peninsula Borough. The landscape is primarily defined by the maritime environment of the Shelikof Strait region, where significant underwater and surface hazards are documented. These include the prominent Katmai Reef to the southwest and the isolated Flat Top Rock further east. The map provides a clear look at the relationship between the remote islands and the complex bathymetry of the Alaskan coastline in the early twenty-first century. This specific quadrangle highlights a section of the sea largely devoid of permanent human settlements, focusing instead on the vital navigation landmarks and terrain features that define this stretch of the Aleutian Range's coastal fringe.
