It's a crater on the surface of the Moon, probably the result of an asteroid impact.
There are not only maps of the lunar craters, there are lunar globes that depict the Moon just as it is. Even better; there is Google Moon! www.google.com/moon

Most lunar craters are impact craters caused by incoming meteors and asteroids. Since our moon has no atmosphere there can be no glaciers or erosion.
Most lunar craters are circular. It takes a very unusual shallow (or grazing) impact to make a crater that is not circular.
Meteorite impacts.
They last forever.
noooooooooooooooooooo!
Craters are formed when asteroids and comets collide with the lunar surface.
There is water inside of craters or ice inside of craters
The lunar surface is made up of rocks and craters of all shapes.
