Beautiful deadly

Do NOT attempt to swim laps...

Yellowstone's thermal pools might look inviting with their aquamarine colour so reminiscent of tropical water, but don't be fooled.

The temperature of the water is only slightly below boiling and the water is extremely acidic. Staff are often on the lookout for people 'hot potting', i.e. illegally trying to have a soak in the pools as if they were hot tubs.

One unfortunate man from Oregon several years ago learned how deadly they could be in the final minutes of his life. He slipped and fell into the water. The high temperatures and the acidity of the water literally dissolved him before his body could be recovered. Ewww...

Hot potting... a good way to thin out the stupid ones...
