The Coso Mountain petroglyphs are the last remnant of a society that started thousands of years ago and lived almost to our present time. And through the artistry and symbolism of these petroglyphs we know that it was a hunter gather society that was based on hunting desert bighorn sheep, and so the desert bighorn sheep loom large in its everyday culture and mythology just as the buffalo hunting societies that once lived on the Great Plains centered their culture and mythology on the buffalo.
And while the rocks and bighorn sheep have changed little, the climate and the people have changed considerably; for one, the climate was wetter back then as the dry lakes that are scattered throughout the desert show, and this, in combination with other factors, allowed the bighorn sheep to become the dominant grazing animal of that time.
