1960 Map of Anchorage A-4

About this map

Chugach National Forest land dominates this 1960 survey, documenting a glacial landscape where massive ice flows meet the saltwater of the Prince William Sound area. The map illustrates the dramatic convergence of numerous glaciers, including the Colony Glacier, Serpentine Glacier, and Stairway Glacier, as they carve through the peaks of the Chugach Mountains. High-altitude landmarks such as Mount Gilbert, Mount Gannett, and Mount Muir overlook the deep waters of Harriman Fiord and Barry Arm. This document captures the mid-century extent of these active ice fields before modern retreat, providing a baseline for geologists and environmental historians studying the Surprise Glacier and Cascade Glacier. The intricate contour work also details the crevassed surfaces and moraine patterns along Doran Strait and Surprise Inlet.
