Navajo Nation Zoological Park - If you have interests about the type of animals that roam the Northeastern part of Arizona, then this is the place. See indigenous birds and animals heard in many Navajo legends. Within the canyon lies over 7,000 archeological sites. Parts of the cliffs are covered with ancient pictographs and huge stone formations rise hundreds of feet above the ground. The Pueblo people constructed cliff dwellings 2000 years ago and then departed due to climate changes, so some claim.
Scheduled hikes are available.
Dinosaur Tracks - About a 10 minute drive west of Tuba City in the Northwest part of the Navajo Nation, you will see a sign for dinosaur tracks. Over 200 million years ago dilophosaurus, carnivorous reptiles made imprints in soft mud which eventually hardened over time and became sandstone. No cost to see them and they're pretty cool. Here you'll find a slab of concrete imbedded into the ground marking the only spot in the United States that four states meet at one corner. In the summer over 2,000 visitors a day visit this monument just to spend about 20 minutes for pictures.
