Explanation: What created this unusual hill on Mars? No one is sure. A good outlook to survey the surrounding area, Siccar Point stands out from its surroundings in Gale Crater. The unusual mound was visited by the robotic Curiosity rover exploring Mars late last year. Siccar Point not only has a distinctive shape, it has dark rocks above lighter rocks. The apparent much younger age of the dark rocks indicates a time-break in the usual geological ordering of rock layers -- by a process yet unknown. The Martian hill is named for Siccar Point on Earth, a place in Scotland itself distinctive as a junction between two different rock layers. Curiosity continues to explore Gale crater on Mars, looking for clues of ancient life. Simultaneously, 2300 kilometers away, its sister rover Perseverance explores Jezero crater, there assisted by the flight-capable scout Ingenuity.

Looks like Utah. Not saying it is, just it looks like it is.

Is there any scale on this picture? Is the hill ten feet above grade or fifty?

It’s hidden by a Wakandan cloaking field.

It looks like it was an overhang that eventually broke off.

Looks like it sticks out into the crater.
Therefor it must be some extremely hard material to survive the creation of the crater.
