Journeyman

I'm another hydrogeologist, but have never been much of a rock collector. The ones I do have are either mementos of a trip, or tell a little geologic story. Or both, like the cross-bedded sandstone I collected on a field trip in central Texas.

I guess my kitchen countertops count, too. They're a metaconglomerate from Brazil with a wide variety of rock types in the cobbles. I can spot metamorphic halos on some of 'em, there's a nice partial meltings that gives a "kissing rock"--lots of entertainment for rock hounds who come to visit.
