About this map

The Katmai National Monument boundary cuts diagonally across this remote coastal landscape, separating the interior wilderness from the tidal reaches of the Shelikof Strait. Surveyed in the early 1950s, the map reveals a rugged maritime environment defined by prominent peaks like Mt Kubugakli and Atmo Mountain, which tower over the expansive Tidal Flat areas of the coast.

Coastal geography is intricately detailed, showing the protected waters of Kashvik Bay, Alinchak Bay, and Katmai Bay. Human presence is nearly nonexistent in this era, marked only by a lone Cabin and the VABM Kubugakli triangulation station near Cape Kubugakli. The map serves as a primary record of this coastal boundary before later park expansions, documenting the precise relationship between the mountainous terrain and the shifting tidal zones of the Alaskan peninsula.
