Does anyone know what kind of "rock" this is... Its actually very clear and bigger than a softball. There has to be someone here who knows "rocks" I know it is not the best picture but its the best i could do at the time

It looks like ulexite bound to some other type of rock.
Is it translucent at all? And/or brittle? |

I think it looks too fibrous to be quartz... |

| quartz has no cleavage. that definately does have cleavage, just not the cool kind. although ulexite is generally more fibrous, i still think it is a good assumption. with out seeing it in hand sample though... it may just be a big chunk of gypsum. |

I'm gonna go with quartz also. But am not a rock expert by any means.
http://en.wikipedia.org/wiki/Milk_quartz
Quote: Milk quartz or milky quartz may be the most common variety of crystalline quartz and can be found almost anywhere. The white colour may be caused by minute fluid inclusions of gas and/or liquid trapped during the crystal formation. The cloudiness caused by the inclusions effectively bars its use in most optical and quality gemstone applications |

| I'm pretty sure it's not quartz. Research time! |

That's my guess as well. I've got a couple of huge chunks of gypsum that look just like that one. |

Well, now it sounds like youve found kryptonite.
