Hello, Milum...

This wind is from the Old Dominion, Virginia. I enjoyed reading your dirt, but was dumb as dirt understanding it. A Wind is, but knows not from whence it comes.

For example, when you wrote, "Mammoth Wallow Hole" theory and the "Exploding Comet", all I could see was some prehistoric beast doing a cannonball into the Tar Pits...

But back to basics: Which is the heaviest of the minerals? And the lightest? I think talc is the softest on the mohs scale and diamond, the hardest.
