1961 Map of Petersburg D-2

About this map

Patterson Glacier and Le Conte Glacier dominate this mid-century survey of the Alaskan coast, illustrating a massive glacial landscape within the Tongass National Forest. The topography shows the ice fields feeding into the Muddy River and Le Conte Bay, while several named summits like Church Peak, House Peak, and Thunder Mountain rise sharply from the glacial valleys. Evidence of human presence is minimal and coastal, marked by a few isolated Cabin and Cabins locations along the shoreline of Frederick Sound. This 1961 field annotation documents the drainage patterns of Bussy Creek and Jap Creek before modern environmental shifts, providing a primary record of the tidewater glacier positions and the dramatic vertical relief of the Horn Cliffs and Thunder Point.
