Near Badwater, after storms in the surrounding mountains drained enough water down to the salt flats to create a rather large lake. But it was only a few inches deep and would evaporate within several weeks.
Scanned from a slide and converted.
Thanks for the comments, Barry and Leon.
The photograph was taken about 10 or so years ago. Definitely before the big flood of a few years ago where roads were washed out and a few people died.
Water can drain into the salt flats from the surrounding mountains even though it may not have rained in the valley itself. I've seen a lake there two or three times over the years.
