Hovenweep's unique towers remind of European medival castles. These Anasazi Indian buildings located along the border between Utah and Colorado in the United States were built hundreds years ago. The structures here are numerous and varied. Some are square, some round, some D-shaped and some measuring nearly four stories all. There are towers, kivas (underground chambers), rooms, granaries, check dams, and farming terraces. There are many theories about the use of the buildings at Hovenweep. The famous towers could have been used as defensive structures, storage facilities, celestial observatories, civil buildings, or any combination of these.

Newspaper Rock is sandstone covered by a thin black patina, known as desert varnish. This rock has extremely dense Native American petroglyphs representing several ancient cultures like Anasazi, Navajo and others. It probably records 2,000 years of human activity in the area. The drawings show human figures, hunting scenes, animals and many other symbols. A cartwheel (shown on the picture) probably represents Sun; a wavy line is a river. But there are still many more inexplicable.
