To find the cave with gold bars in Red Dead Redemption 2, go to a location north of Donner Falls in Ambarino, near a "mysterious hill home" and marked by two trees. Inside the cave, find the "Strange Statues" puzzle: four statues surrounding a central one. Press the buttons on the statues with two, three, five, and seven fingers (or a one-armed statue). A compartment in the center statue will open, revealing three gold bars that can be sold to a fence for $1,500 To get gold bars from a train in RDR2, locate the derailed train wreck south of Cotorra Springs and north of Valentine. You'll need to climb up the rocks beside the wreck, navigate some ledges, and make a few running jumps to enter a vertical train car. Inside, you will find two gold bars, along with other items like aged pirate rum and Valerian root.
