Here the Colorado River is cutting through an obvious anticline. The anticline was created when salt, deep underground, squished around and pushed sediment up.
What makes this image interesting is the potash plant. The right side of the picture shows the potash plant where they pump water down into the Paradox formation (salt from the Permian) The left side of the picture shows the vivid blue evaporation ponds. Water filled with paradox brine comes up to the surface evaporates away and leaves the salt behind.
