If you don't have a deep ocean trench, but you do have a meson gun on
the shore and some free time... then you can have a deep ocean trench.

But, you need an ocean.

On the other hand, if you've got antigrav technology, and ice in the
asteroid belt, and some free time.... then you've got some really big
lakes.
