1951 Map of Chandeleur Light

About this map

Chandeleur Light stands as the primary landmark on this narrow island chain within the Breton National Wildlife Refuge at the mid-century. Based on aerial photography and hydrographic surveys from the 1950s, this chart captures the shifting coastal morphology of the Chandeleur Islands before decades of storm erosion further altered their profile. The barrier islands serve as a critical boundary between the open Gulf of Mexico and the shallower Chandeleur Sound. This survey provides a precise look at the 1951 shoreline and the surrounding bathymetry, marked by depth curves and soundings that define the navigational hazards near the light station.
