During our first visit to Petrified Forest National Park, I asked:
Here’s what I don’t get about petrified wood: how come when the organic material is replaced by minerals, it generally comes out still looking like wood? I mean come on, minerals come in every color of the rainbow. Why don’t we see bright yellow or red petrified logs?
Thanks to this exhibit at Jim Grey’s Petrified Wood in Holbrook, AZ, we now know that petrified wood can be in other colors. Rarely.
