Background Information

As the story goes, some time during the late 1800’s a few renegade Indians attacked and killed the miners of a small hydraulic mining operation near the town, in California. While the mining operation might have been small, they were doing very well. The Indians apparently stole about one hundred pounds of mostly nugget-gold from the dead miners.

Since the Indians were on foot, and also carrying a very heavy load, it did not take long for the posse to catch up with them. In fact, as a last ditch effort to get away, the Indians stashed the gold somewhere so they could move faster. When the posse caught up with the Indians, only the Indians knew where the gold was. The men in the posse told the Indians that they would not be hung for their crimes if they would tell where they hid the gold. The Indians told the posse that they had hidden the gold in Cave #2-Hall City Cave, CA. Then they were promptly hung right on the spot.

As it turns out, Cave #2 - Hall City Cave has a deep, submerged cavern at the back of the cave. The cavern is said to be bottomless, because no one apparently has ever been able to get to the bottom. And of course, not the posse, or anyone else, ever found the gold. Did the Indians hide the gold somewhere in the cave? Did they just dump it into the bottomless cavern to get rid of it? Did they have some secret hiding place in the cave, perhaps underwater? Or did they hide the gold somewhere else?
