I finally decided it was time to officially walk away from this piece.  It's a panorama composed of 9 separate (stitched together) photographs taken moment before this approaching dust storm and super storm behind it completely gobbled up the entire area and forced me back into my vehicle on Saturday evening.  I managed to get a little over 280 photos of this wall as it progressed towards me before I had to stop all photography and seek out shelter in one of our automobiles.
