Iron Door Cave

Lots of mystery surrounds Joshua Tree's Iron Door Cave. The cave itself is about 120 square feet with enough room to stand up in and a little air hole at the far end. Nobody really knows how the iron door got there or what it was for, but the leading theory says that Bill Keys used it as a cold storage room for his dynamite. Another story says that he used it to store gold from nearby mines. But the craziest theory says that Keys used it as a prison to lock up his schizophrenic son. Wow! The location of the cave is really close to the Hidden Valley Campground, but it is extremely well hidden between the boulders. You can easily walk right by and never see it. Fear not, the coordinates below will get you to the front door, just don't get locked inside. Lat/Long: 34.02078, -116.165207
