I was highly recommended to enjoy a hot -mud bath in Calistoga, California. To immerse in hot volcanic ash from nearby Mt St Helena. But we didn’t have much time.  Instead we checked out the petrified redwoods, hence we saw the largest petrified trees in the world.

The trees “turned into stones” when three million years ago, the eruption of Mt St Helena felled giant trees and covered them in ash and mud. Over the years, the trees were petrified. It was like looking into huge boulders. I wouldn’t have known the difference between petrified trees and boulders.

The experience reminds me of a film “Journey to Italy” with Ingrid Bergman. There was a scene where archeologists dug up what looked like petrified bodies – human bodies covered under layers of ashes in Pompeii.
