About this map

The coastal shoreline of the Alaska Peninsula meets the Shelikof Strait in this early 1950s survey. This area is defined by the deep indentations of Wide Bay and Portage Bay, separated by high coastal ridges including the prominent Cape Igvak. The presence of the solitary Lee Cabin near the mouth of Des Moines Creek suggests the seasonal activities of trappers or mariners in this remote maritime landscape, which relied heavily on coastal navigation before the expansion of interior infrastructure.

Offshore, a chain of islands including Terrace Island, Hartman Island, and Titcliff Island creates a complex system of channels such as the East Channel and West Channel. Navigation is supported by a Light at Cape Igvak, marking the entrance to these protected waters. The terrain transitions from coastal Tidal Flat zones at the mouth of Big Creek to steep peaks, including a summit at Vabm 1923, providing a clear view of the navigational hazards like Channel Rock.
