1943 Map of San Ysidro

About this map

The international border between the United States and Mexico anchor this survey, which traces the southern reaches of San Diego Bay during the height of the Second World War. The landscape is defined by the coastal transition from the Silver Strand peninsula to the inland mesas, with the Tia Juana River and Otay River carving through the terrain. Civil and military infrastructure is prominent, including multiple landing fields and the expansive Salt Works at the bay's edge.
