Pools of Potassium

This water color in the middle of an otherwise colorless landscape doesn’t even look real, but I assure you it is. Scientists were confounded by these pools when they first came across them. They couldn’t reconcile how such color would show up here, of all places. Eventually, after discovering more, they realized these pools formed in areas once underwater. When the water eventually receded from the land, it left these pools of potassium behind.
