I found this short you-tube on the geology of Monchique, Portugal and it's quite good, if you want to take a look. Monchique is in the s/w area of Portugal and is a geothermal area. People go there to enjoy the sulfur baths and get fresh spring water too much like they used to at the Geysers, but they go to Calistoga and Sonoma presently to enjoy the same.
