Yeah I guess you can look at ancient craters from meteors or volcanos to see how it would look.

Can we? I'm not under the impression that those were ever terraced[1] like open-pit mines. But come to think of it, terracing itself qualifies as a megastructure[2]. Where the Long Now clock is an offbeat art project, rice paddies are crucial for nutrition for a great many people and they've already been around for at least 2 millenia. As times get lean, I can imagine pilfering the Long Now clock for parts; but those rice paddies will only gain importance.

  Terraced open pit mines and rice paddies require an enormous amount of maintenance. The terraces are not naturally stable. Rice paddies will quickly silt-up, then flood and collapse in heavy rain. Open pit mines will fill with water. The sides will collapse. In the desert, they will fill with dust. Deserts often have flash-floods following thunderstorms. They might remain recognizable as hollows, but not much more.
