In San Pedro CA there's a beach called White Point Park, named for the mats of white sulfur oxidizing bacteria that grow in geothermal spring water. A Japanese family ran a bath house with the water from a geothermal spring but an earthquake damaged the flow and then being sent to internment camps ended it. I was gazing in the tide pools there when I got a whiff of sulfur, like at a hot spring, and followed my nose to a tide pool full of white fuzzy sulfur oxidizing bacteria (I think).<p>My pic:
