Cut open this nodule today - nothing exciting, but thought it was interesting that the Quartz deposits alternated between macro crystalline and cryptocrystaline multiple times during formation. It's cool to see the pointed crystal terminations and the rounded botryoidal formations. Anyone know what condition changes would have caused this? Temperature? Saturation level?

Yes, Yes, & the length of time in centuries that the crystals had to grow. It may not be beautiful color wise, but that's a beauty of a specimen to sit on the shelf.

Another amazing piece of stone.  I find it so hard to comprehend something that "usually" takes millions of years to form and all the conditions that caused it.  Maybe a volcano erupted at one time and then another time there were earthquakes and maybe another time a TRex stepped on it and finally a UFO landed on it and their incredible and uncomprehensible star drive messed with its molecular structure to finally create it as you found it.  Millions of years and endless possibilities of what caused it to end up like it did.
