Explanation: What caused these Martian rocks to be layered? The leading hypothesis is an ancient Martian lake that kept evaporating and refilling over 10 million years -- but has now remained dry and empty of water for billions of years. The featured image, taken last November by the robotic Curiosity rover, shows one-meter wide Whale Rock which is part of the Pahrump Hills outcrop at the base of Mount Sharp. Also evident in the image is cross-bedding -- rock with angled layers -- which were likely facilitated by waves of sand. Curiosity continues to find many layered rocks like this as it continues to roll around and up 5.5-km high Mount Sharp.

The cover art has gone through many incarnations.
So they keep saying water caused all these things, couldn’t it also have been liquids of other kinds since there really isn’t much water to be seen now (except in polar caps)? Titan is filled with liquid methane. Maybe I’m missing something, but why is water always assumed for the cause of these formations?
Is that a K-T layer I see there?
