Mares are indeed astonishing!

The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth’s surface. Moon’s surface has not been modified since early in its history, so most of its craters are still visible.”

Mare Orientale

The Moon’s vast Mare Orientale impact crater is 200 miles wide, one of the largest in the solar system. The outermost circle of the crater is the Cordillera Mountain scarp, a line of cliffs about 560 miles wide. At 3.5 miles high in places, these are the highest mountains on the Moon.
