Re: cauliflower-shaped rock some type of quartz?
coincidence...i have carried this rock all over the united states with me! since i was
a child in southern Indiana i have wondered what this rock is. my grandfather and i were hiking along a ridge and found this rock that looks exactly as you describe it. my rock also looks like a petrified cauliflower...we have always referred to it as the brain rock. if you receive any response as to what it is i would love to know.
