About this map

Iliamna Lake dominates the upper half of this mid-century survey, its expansive waters meeting a complex shoreline of inlets and low-lying wetlands. The southern interior is defined by the winding paths of Pecks Creek and Belinda Creek, which snake through a landscape marked by numerous small, unnamed ponds and glacial depressions. This specific terrain pattern reveals the transition from the high-energy shoreline of the lake to the water-saturated lowlands of the Alaska Peninsula.

A single Winter Trail provides the only recorded overland transport route, cutting across the marshy interior between the major creek drainages. Offshore, Big Island and the smaller Shoulderblade I stand as distinct landmarks within the lake. The absence of permanent settlements or improved roads in this era underscores the seasonal nature of travel and the reliance on waterways and traditional trails for navigation through the wilderness.
