1950 Map of Icy Bay

About this map

Malaspina Glacier dominates the northeastern corner of this coastal survey, where the frozen landscape meets the waters of the Gulf of Alaska. The map captures a critical maritime and glacial interface in the mid-century, detailing the complex drainage patterns of the Yahtse River and Big River as they flow toward the sea. Most of the sheet is dedicated to the vast bathymetry of the Pacific Ocean, providing a specialized look at the underwater contours and coastal hazards along the Alaskan shoreline.
