I like the Utah version better,it's a harder stone..... http://www.so-utah.com/grand-canyon-kanab/kanab-utah/wonderstone/
Sometimes called picture sandstone, or landscape sandstone. I had a beautiful piece, which I simply lost. I've been looking to replace it but can't find anything that measures up. I have this piece, about 6" square, that I would guess is from Utah, but it pales in comparison to what I lost.
