The Mojave Megaphone, sometimes called the Sentinel Enigma, has been a mystery for decades. It sits high on a rocky ridge in one of the most remote parts of the Mojave Desert. This odd, welded-steel structure looks out over the empty landscape, and no one knows who built it or why.
Some people wonder if it was part of a railroad warning system, a military sound monitor, or a surveying tool lined up with desert landmarks. Others even believe it might have been used to communicate with UFOs.
But a rare clue from a 1990 Desert Dispatch newspaper article may finally shed light on the truth, suggesting it wasn’t a megaphone at all, but something far more unusual… a massive desert drum, powered by a generator and carried up the mountain by hand.
Join us as we explore the ruins of Crucero, hike to the Megaphone itself, and separate fact from desert legend in one of California’s strangest modern mysteries.
