China Lake Petroglyphs: The World's Densest Rock Art Behind a Navy Fence

Somewhere behind the security fence of the Naval Air Weapons Station China Lake, in the Coso Range of the Mojave Desert, there are more than one hundred thousand petroglyphs. Scholars estimate the count at over one hundred thousand individual images. The actual number may be higher. No one outside a small group of archaeologists with supervised military access has seen all of them.

The petroglyphs span an extraordinary range of time. The oldest images date to perhaps sixteen thousand years ago. The most recent were made approximately one thousand years ago. They show bighorn sheep in numbers that suggest the Coso Range was important hunting ground. They show anthropomorphic figures, human-like forms with elaborate headdresses, in postures that archaeologists interpret as shamanistic. They show geometric patterns whose meaning is no longer recoverable. The people who made them were the Numic-speaking ancestors of the Timbisha Shoshone and related desert peoples, and the Coso Range was, in their spiritual geography, a site of unusual power.

This is the densest concentration of rock art anywhere on Earth. Not in California, not in North America, but anywhere. The ranking is not in dispute.

The Navy acquired this land in nineteen forty-three. The mission at China Lake was weapons development, specifically the heat-seeking air-to-air missile program that would produce the Sidewinder. The petroglyphs were already there when the military arrived, already behind the ranges where test aircraft flew. They have been behind the fence ever since.

Scholars can apply for supervised access to study the Coso Rock Art district. The application goes through the military. Access is granted selectively, for research purposes, in the company of security personnel. The general public cannot go there. Not as tourists, not as curious drivers, not as descendant community members without the same application process.

The National Historic Landmark designation, awarded in two thousand one, is the federal government's acknowledgment that the petroglyphs matter to the national heritage. The landmark designation does not change who controls access.

The situation is what it is: the most significant rock art concentration in the world sits inside a military installation in the California desert, visible to almost no one, funded by the same taxpayers who cannot visit it. If you are driving near Ridgecrest on Highway One Seventy-Eight, you are approximately as close as most people will ever get.
