What’s part geyser, part mud pot, and all creeping, unstoppable natural disaster? The Niland Geyser, known as the world’s only moving mud spring. Dianna explores this geological mystery in the video above. Although the mud spring has been known for years, it was only in 2016 that it started moving toward railroad tracks and a state highway. So far engineering efforts to stop it have failed, so engineers are instead working to mitigate its effects on infrastructure.
That’s a tall order when dealing with a pit of unknown depth that’s constantly bubbling with deadly carbon dioxide. The spring managed to move past a 75-foot-deep wall and, on another occasion, sent heavy drilling mud flying skyward from its built-up pressure. Check out the full video to learn more.
