The sea was born by accident 100 years ago, when the Colorado River breached an irrigation canal; for the next two years the entire volume of the river flowed into the Salton Sink, one of the lowest places on Earth.
The new lake became a major tourist attraction, with resort towns springing up along its shores. Yet with no outflow, and with agricultural runoff serving as its only inflow, the sea’s waters grew increasingly toxic.
Farm chemicals and ever-increasing salinity caused massive fish and bird die-offs. Use of the sea for recreational activities plummeted, and by the 1980s its tourist towns were all but abandoned.
