So western New Mexico is the same as eastern new mexico. Arizona seemed drier and less green, but more mountainous.
My big stop was a petrified forest national park. It almost like a combo national park- the top half has part of the painted desert and the southern part more of the petrified forest. The petrified trees were nice especially when you get close ups and can different colors and minerals causing those colors. The wood petrified into a rock like material when in was flooded over 200-300 millions years ago. When it was submerged, it coated with silica and various other elements. The silica caused the petrification and other elements such as maganese and iron gave different colors. (the former more blue and the later more reddish). During my park drive- I even saw a raven out and about, and the old route 66!
On the other had the painted desert was amazing. The best part was the blue mesa where you drove up to the top and viewed both petrified forest and painted desert and then could hike 1 mile each way down. I have to tell you the hike was totally worth it to see the different shades of oranges and blues up close.
Interesting, current policy would not allow something that I saw- concrete under a petrified tree. Policy now is to allow nature to take its course. In the early 1900's-1930s policy was different. First they built brick supports then concrete. This was all for a log that was acting like an arch in the desert, now if it fell, it falls, but the concrete still supports it.
Duirng my drive and hikes I could've seen a cactus and not realize it, but between Flagstaff and Phoenix (closer to phoenix) I saw a ton of Saguaros-those THE well known cactus that grows tall and branches with arms.
Next stop- San Diego!
