2020 Map of Stepovak Bay D-5 SW

About this map

Kupreanof Peninsula dominates this maritime landscape along the southern coast of the Alaska Peninsula, where the waters of Stepovak Bay meet steep coastal elevations. The transition from the tidal reaches of Stepanof Flats to the narrow land bridge at Granville Portage illustrates the geographical challenges of this shoreline. To the north, Smoky Hollow sits tucked behind James Island, while the southern reaches are drained by Osterback Creek. This modern survey by the U.S. Geological Survey captures the intricate coastline and relief of a region where the borough boundary between Aleutians East and Lake and Peninsula divides the rugged interior. The map detail highlights the isolation of landforms like Road Island and the complex topography that historically necessitated portage routes across the peninsula's narrowest points.
