In addition to one of the world's largest concentrations of petrified wood to park includes the multi-hued badlands of the Chinle Formation known as the Painted Desert, historic structures, archaeological sites and displays of 225 million-year-old fossils.
This was not one of my favorite sites. I just didn't find it particularly interesting or beautiful. Meteor Crater was worth going to but is run as a private business and it makes me glad the National Parks are not run that way. Meteor Crater was created when a meteor struck the earth millions of years ago.
The highlight of my trips (in this area) was Sunset Crater. I also got a very quick visit to Walnut Canyon National Park: I got there 15 minutes before closing. I plan on going back to Sunset Crater and Walnut Canyon but not the Petrified forest or Meteor Crater.
Wupatki National Monument was a worthwhile and enjoyable small site. These sites together make for an interesting aray of nature and historical sites in the general area of Flagstaff, Arizona.
