I hike to a desert oasis in the Mohave Desert of California where a crack in a cliff wall has scalding hot water seeping down the cliff wall, which happens to have a high lithium content. There is a creek the hot water flows into, and people have sand bagged various hot pools to soak. The placed is called "Deep Creek Hot Springs", and it internationally famous. About a decade ago I looked up the lithium content, it is published, and everyone there talks about how calming the hot springs are, lasting for days.
