Walking on the travertine cone that spreads out from the fount of Old Faithful in Yellowstone National Park is clearly marked as being illegal, but that didn't stop a man from doing just that and appearing to urinate into the geyser.After everything ended, the man reportedly walked to the parking lot. A park ranger met him there and arrested him, according to WTHR-13. He was charged with violations, including being off-trail in a thermal area.He has been released on bond.Vertical Video Warning
