Here’s the Wednesday Geology Picture as part of Evelyn’s meme. Close to the Arches National Park in Utah there is Potash, a bizarre place with saltworks that shimmer in incredible colours. Here, salt is leached from the underground and then dried in the sun. The roads that lead to the Dead Horse State Park have to cross little creeks at times, where the salt precipitated and formed glittering crystals. I had the opportunity to do some research in that area with my great colleagues Heijn and Michael in May this year.Larger Map
