The Gates of Hell

Driving to the badlands, trying to beat the dark to set up camp.  The storm had been on the prairie horizon for four hours.  I had asked Rattlesnake Joe to stop for pictures at least ten times and he was patient, but we were losing light.  So, I had my telephoto lens on and took this picture out the window at 80mph on Route 90.  The Gates of Hell will not prevail.
