On a Scale of 1-10 I give this thread a 1 for being the weakest thread ever. What do the rest of you think?

Of course, that means it would push "weak rocks" off the list of weak rocks, but does anyone see a problem with that?

Well, I sort of enjoyed it, so those electrons were not wasted.

In fact, I think they were really pretty sober.

No, that would be #1, and the technical term is "Fisher Towers".

I was put under the impression that high quality basalt is definitely better than crumbly granite, and the best basalts can be even harder than good quality granite.
