There was the Orchard—a cavern full of stalactites and stalagmites that had fused together into slender columns. And less than a day later, we came across the Dancehall, a long cave of pink quartz with a floor so slippery we had to crawl over it, occasionally sliding to our bellies. Then there was the eerie, partially submerged iron portcullis we called the Angelgate. It was flanked by two winged stone figures, their heads bent, their hands resting on marble broadswords. The winch worked and we passed through it without incident, but why had it been put there? And by whom?
