Death Valley National Park, California. Crystallized salts compose the jagged formations of this forbidding landscape. Deposited by ancient salt lakes and shaped by winds and rain, the crystals are forever changing. Salt continues to be deposited by recurring floods that occasionally submerge the lowest parts of the valley floor. On a warm day you may hear a metallic cracking sound as the salt pinnacles expand and contract. Walking on the Devil’s Golf Course is very difficult as the bottom surfaces are narrow and uneven. A fall can result in painful cuts. I got scratched up a bit myself. Those salt formations are surprisingly hard and sharp.
