This photograph of a Native American Petroglyph was taken at Comanche Gap, in New Mexico's Galisteo Basin.  One of the amazing things about the New Mexican landscape is that virtually all black lava rock outcroppings of any size, have at least a few, and generally more of these engraved images.  Placed there, the landscape thus becomes both a more open book, and the setting of the liturgy.  The petroglyph images are available to those of us curious enough to vist.
 
The image on the rock was most likely created by a inhabitant of a nearby pueblo. That pueblo, along with it's former inhabitants, exist today only as spirit.
