As they say, monuments attract attention. I know if I spot a large black slab of granite-like stuff, I'll be checking it out. Even if it's on the moon. With explosives, if need be. (as per Asimov's 'The Sentinal'.) I like they idea of burying waste deep in salt flats. Works for witches & warlocks, nuke waste shouldn't be a problem. It's not as if you'll be growing corn there.
