I Found the Mystery Object Bolted to a Mojave Rock

Bolted onto the top of mountain in the Mojave Desert is a giant rusted megaphone. There's no plaque, no road sign, no person that admits to putting it there. For more than 30 years, internet sleuths have tried to explain it. A railroad warning siren? A WW2 acoustic mirror? A Cold War chemical alarm? A treasure marker? A UFO contact device? I drove out to find it, climbed up to it, and walked through every theory the desert has thrown at this thing. This is the Mojave Megaphone.
