thanks for the good documentaries Planet Kaos, the Death Valley Doc. had some really good geologic information! Borax forms only in fresh water the lowest point in USA = Badwater Basin @ -282 ft below sea level (-92 meters) the floor of the valley is dropping faster than the valley floor is building up with sediments One of the thinnest crustal regions of the world @ 15 miles thick vs Mt Everest & Himalayas @ 45 miles thick Death Valley gets 2 inches or less rain annually. (the reasoning why the ancient fresh water lake, Lake Manly, that once filled the valley to a depth of 450 feet, is long gone) as tested in experiments, there is 150 inches of water evaporation capability per year in DV.. ergo evaparation was much more than replenishment = LAKE MANLY GONE Hottest location in USA, hit 135 degrees F in early 1900s, easily hits 120F or more annually in summer Death valley was a shallow ocean floor for many millions of years Volcanic activity from the crustal subduction zone of the Pacific Ocean plate & North American plate to the west, caused volcanic activity that created many of the mountains that you see in DV (up to 11,000 ft peaks yet nearby 2 miles away is -282 ft below sea level valley)  Keep posting these videos THANK YOU!
