We returned to Petrified Forest National Park after 30 years.  We walked every trail and even spent a few hours on the valley floor of the Painted Desert Wilderness Area.  I suspect the rocks haven’t changed much but we experienced it a bit differently this time.  The geology is very cool.  Petrified wood is amazing.  Petro glyphs make one really wonder about those civilizations who long ago called this place home.  We even saw some wildlife: lizards, a snake, prairie dogs, a pronghorn antelope and a nice assortment of birds.  All in all, definitely a place to check out.  At least every 30 years of so.
