Texas Canyon

 Going east from Tucson on Interstate 10 the first rest area you will come to is at the top of a hill in the Texas canyon area.  It's pretty hard to not notice it.  On both sides of the road are mounds of round boulders kind of scattered about.  On the west bound side they are higher and more pronounced.  This image was taken from the rest area on the east bound lane and looking south.  Gives you an idea, but not nearly as dramatic.  Some day I''ll stop on the west bound side and get some shots.
