1948 Map of Dixon Entrance C-1

About this map

Prince of Wales Island meets the open waters of the Dixon Entrance and Clarence Strait in this topographic study, based on 1948 aerial photography with minor revisions through 1985. The coastal fringe is defined by an intricate network of waterways like Nichols Bay and Brownson Bay, separated by high points such as Nichols Mountain. The map details the transition from the protected timberlands of the Tongass National Forest and the South Prince of Wales Wilderness to the treacherous offshore features like Nunez Rks and White Rks. Mariners and local historians can trace the specific naming of coastal landmarks, from Cape Chacon at the island's tip to internal passages like the Bert Millar Cutoff and Minnie Cutoff, illustrating how the marine geography dictated movement and naming conventions in this maritime environment.
