Petrified wood

There is something about petrified wood that intrigues me. The definition of petrify is to convert organic matter into stone or a stony hardness  by the infiltration of water and the deposition of  mineral matter.  It always looks like a decoration, put in just the right spot.  I wonder how long it has been there. Was it blown there? Dragged there?  How long was it living?  I think we saw this on the Tonto West day hike out of Indian Gardens in the Grand Canyon.
