Colorado's state rock is, specifically, Yule Marble. The state mineral is Rhodochrosite, and the state gemstone is Aquamarine.

If New York has a state rock it should be limestone. We did a walkway on the north side of our house using PA Bluestone @ 30ยข a pound. Back north I could find an old stone fence out in the boonies and take what I could haul. One of the few drawbacks of living on a giant sand bar.

I was going to say limestone for Florida, but apparently we don't have a state rock. I am happy that our state legislature isn't wasting time on something like this.

Texas has a state rock. Petrified Palmwood. I wonder why it isn't on the list? Maybe it isn't "official"?

I think Wyomings state rock should be coal, sandstone, or some sort of fossil.
