Shows the elevation of the martian landscape.
red = hill, blue = valley
the big blue crater at 60°E, 45°S is probably an old impact crater from an asteroid and is 4 km deep!
The highest mountain on Mars is olympus mons at 20°N, 130°W with an altitude of 21 km above planet-wide average.

That is actually what scientists speculate, too! It is noteworthy that the big crater at 60°E, 45°S is almost directly on the other side of the planet as the big mountains near olympus mons, so it’s easy to guess that the same impact that caused the crater, also pushed the mountains up. But, it’s speculation. i don’t know for sure.
