The channels of the Leron change as often as every hour. Fifteen minutes after a safe crossing at one point, it may become a tearing torrent.
What can happen to vehicles caught in it was shown by the experience of one of the Signal Corps soldiers fording the Leron. In a shallow portion he perceived an automobile radiator cap lying in the mud. He stooped to pick it up but he couldn't budge it, because attached to the cap was a tractor, completely buried in the mud. It was believed to have been lost by an engineer unit that had tried to get through previously. Efforts to dig it up were futile.
