Epecuen, Argentina was once a popular lakeside resort town, known for its saltwater baths and spas. It was especially popular among Argentine Jews from nearby Buenos Aires, who found the lake, which had 10 times more salt than the ocean, and was buoyant, similar to the Middle East's Dead Sea.

But then in November 1985, after a series of wet winters, the lake flooded the town. A retaining wall failed and the salty water submerged the streets. Now the waters have receded, exposing what remains of the former resort.
