Rare Pink Dolomite
But we were speaking of dolomite. Even geologists don't agree on what it is, except that it's calcium and magnesium somehow mixed, and rarely there are pink examples of it, probably from being mixed with a little iron. A dryer-sized chunk of petrified mud had this chip broken off of it, revealing lovely sparkling stone bubbles (saddles) and glittering crystals.
I learned today that flipping flat rocks looking for creatures or fossils underneath them -- and not replacing them-- destroys the flora and fauna that lived in that environment. I was never in the habit of flipping rocks but now I know for certain that it's bad manners.
