1963 Map of Chignik A-6

About this map

The hydrological drainage of the Alaska Peninsula dominates this 1963 survey, where several large water bodies define the landscape. Sandy Lake sits prominently in the western portion of the quadrangle, serving as a significant geographical anchor. From this basin and the surrounding high ground, the Sandy River and Muddy River trace their paths toward the coast, while the Milky River flows through the southern terrain. This map, based on aerial photography from the late 1950s and early 1960s, documents the natural state of these river systems before later environmental shifts or modern changes, capturing a pristine view of the Aleutians East drainage patterns during the mid-twentieth century.
