This is by far the largest and most well preserved Anasazi Indian Ruin in the U.S. Petroglyphs line the canyon walls. No one really knows why such an extensive site was abandoned.
There is a campground here for campers, but be aware of the twenty mile road which will be impassable should it by some slim chance rain.
There is also an observatory with official guided viewing in the dark night sky of the New Mexico desert. The Anasazi were astronomers, seeing here is often good.
