Walking with Superman: Day 130

Racetrack Playa is a region in Death Valley National Park, where stones slide mysteriously across the ground, carving tracks into the dry lake bed without any apparent propulsion. Several mechanisms have been hypothesized for the rocks' movements, but none have been definitively confirmed. But geologists have stepped up their observations in recent years, noting that the once apparently aimless tracks have been converging. Today, for the first time, three of the stones are expected to collide, and Superman plans to observe the event alongside the scientists. But when he lands, the stones become a lot more active! Not merely three, but dozens of the sailing stones lift into the air and collide with one another, changing shape and taking on a familiar, if shrunken, form. Years ago, when Superman had been split into a pair of energy beings, he sacrificed himself to save the world from three giants intent on remaking it. Now, standing before him, smaller but no less recognizable, is Cabraca, one of those three giants, reconstituted from the sailing stones of Racetrack Playa! The relentless mountain destroyer has returned to finish the job it started years ago, and its first goal is to kill Superman!
