High on the cliff above Badwater Basin in Death Valley, there's a small sign that reads SEA LEVEL, and everyone on the boardwalk below is standing 282 feet beneath it, with no ocean anywhere in sight. Stranger still, the salt under their feet isn't the real bottom. The true rock floor of Death Valley is buried miles deeper.

These are 10 pieces of the answer, each one from a measurement or a named study. They include a 1950s evaporation pan that lost almost 13 feet of water in a single year, an Ice Age lake that came back in 2024 long enough for kayakers to paddle the lowest point in North America, and a fault that drops the valley floor in sudden jolts thousands of years apart.
