(AP) - Ruins have begun to emerge from the sand in San Francisco, puzzling beachgoers.
The San Francisco Chronicle reports that storms and high surf at Ocean Beach have exposed a concrete seawall, about a city block long and 3 to 4 feet tall, along with two sets of cobblestone steps and some weathered wood.
Western Neighborhoods Project executive director Stephen "Woody" LaBounty says the city tried several times to build a seawall, including a wooden one that was destroyed in a 1939 storm. Pieces of that structure, along with a concrete wall built in 1941, began to reappear last month.
LaBounty says the steps were part of a pedestrian tunnel constructed in the 1920s to allow beach access. The tunnel was dismantled about 40 years ago and became buried in sand.
