Julie Garcia's nephew Isaiah dug this piece of petrified wood with quartz crystals on his property at Bluewater villiage.  Here is what Virgil Lueth had to say about the wood.

1.     The tree was most likely Araucarioxylon arizonicum, the most abundant
tree type in the Chinle Formation. The village of Bluewater is nearly
surrounded by the Petrified Forest Member of the Chinle Formation (Triassic)
according to the state geologic map.

2.     The tubes may indeed be capillaries or possible insect borings in the
wood.

3.     As I mentioned in question 1, it is probably the most common type of wood
in the area and not altogether unusual for New Mexico. However, large
colorful pieces are always in demand from rockhounds.

4.    The smoky quartz lined pieces are smoky due to pyrite inclusions.

Check out the Petrified Forest National Park website, much of the
information holds for the Prewitt area:
