It looks like any other rock in the middle of the desert, the one big difference is what you see behind it. Yes, those are tracks left behind by the rock.. The problem is that this is in the middle of Death Valley, CA where there is virtually no life at all. What you are looking at above are what are known as Sailing Stones and there are a few places in the world that have them, the most famous of them all is a place called Racetrack Playa, a dried up lake bed in the middle of Death Valley. When you come over the ridge line of this barren tundra you will see that the playa is littered with these rocks and their trails, some of them almost 1000 feet long.
