Black and white image of an abandoned steam tractor. Description from Special Collections accompanying image: "According to the story told, this was one of the first three tractors ever built. One was shipped here to Eldorado Canyon to move ore and one was shipped to Death Valley for the Borax works (it is still in Death Valley). The other one was sent to South America to a mine. The one in Death Valley supposedly worked out fairly well being used mostly in sand. This one, it is told, was not too successful. The drive mechanism was by way of teeth on the inside of the big black wheels, driven by a pinion gear at the top. Small stones fell into the wheel and stuck in the grease necessitating frequent stops to remove the stones. The driver stood on a platform at the rear. May 1947."
