PetrogylphsThere are a large number of petroglyphs in the surrounding mountains. No one knows for sure what they mean exactly. Where they the records of a people? Where they symbolic magic? A kind of show a successful hunt and you'll have one sort of thing. Whatever they were, they speak to us from centuries ago. The Coso Range on the China Lake Naval Weapons Center has numerous examples of this ancient rock paintings. Unfortunately they are within the confines of the military base and they only have guided tours twice a year, spring and fall. These mountains are centrally located in what was the historic territory of the Western Shoshoni. In fact, Coso is the Shoshonean word for fire. There is indeed a great deal of evidence of volcanic activity in the area. Cinder cones, basaltic flows, and hot springs all can be found here. There are mainly two techniques for putting pictures on rock One is applying pigment to the surface by making a primitive "paint". These are uncommon in the Coso range. Long ago many of the rock surfaces in the area oxidized to dark brown or black finish. The second method involves chipping, pecking away at, or incising the surface until the lighter rock face is exposed. Usually the term refers to the size of the instrument. Chipping would have been done with a large rock hammer. Pecking was done with pointed rock, either holding it and striking the rock face or by placing it against the rock and hitting it with another larger rock. Incising was done with a narrow stone tool that was rubbed back and forth cutting a line. A variation of the second method was to chip or incise the outline of the design and then scrape or sand away the dark rock within the outlines with the edge of a sharp rock until the dark surface was abraded away. Pictures could be made using primarily one method or a combination.
A very sad and tragic aspect of most things abandoned in the desert is the subsequent vandalism. Many examples of rock art have been defaced and some smaller examples have been removed. We must try to preserve these images for future generations so that they can also look at them and wonder about the lives and hopes of the people that made them.
