Owned by the Commander of Fort Rosecrans During World War II.
This detailed map of San Diego and its vicinity was created by the United States Geological Survey under the Department of the Interior. The map highlights the topography and urban layout of San Diego, including surrounding areas such as the Pacific Ocean coastline, the U.S. Naval Reservation, and various residential and commercial districts. It features topographical contours to indicate elevation changes and detailed urban planning with streets and infrastructure clearly marked. The map also shows significant natural features, including hills, valleys, and waterways. The scale of the map is approximately 1:31,680.
The map was owned by Colonel George Ruhlen, who was commander of Fort Rosecrans during World War II and was intimately involved in defending San Diego during the war. In addition to his role during wartime, he was a passionate student of California's historical geography, especially as related to the military.
This map includes a pencil annotation noting the Coronado Beach Reservation 1897, and one noting roads and bridges being built over Mission Bay shortly after the map was made.
