One found many years ago. Not sure about the outer crystalline look. But it was one of those rocks you just pick up.

Hi Chase
I re-inserted your picture here too.
That's a type of concretion often found in sandy desert environments, formed when mineral-rich water is concentrated by evaporation... in a shallow salt basin for example. It's a mixture of sand with planar crystalline gypsum or baryte (or often both) colloquially known as a "desert rose".I keep six honest serving-men (they taught me all I knew); Their names are What and Why and When and How and Where and Who.

Wow those are cool...I would have grabbed em also. I have a whole bunch of rocks that I picked up just based on the neat look. Hey, being the season they kinda remind me of some of those once a year Christmas treats the Aunts/Grandmas would make...nice rocks dude...The chase is better than the catch...
I'm Frank and I'm from the flatlands of N'Eastern Illinois...
