You want color ???
You wamt solid cutting rock ???
This  Is Your Rock !!!!
 
This chunk of Utah petrified wood has the colorful and solid agate that the deserts around the Henry Mountains are famous for. My dad found this rock many decades ago when there was still rock like this to be found out there. You won't find many like this today.
 
The reason there is so much good material around the Henrys is that they are a late blooming igneous laccolith that has punched through the surrounding Colorado Plateau sedimentary formations ... the same formations that have yielded Yellow Cat wood, agatized barites, and dinosaur bone ... and tilted many of them up to expose the formations in deep canyons.
