A collection of 29 placemarks near Area 51 in Nevada of strange circular features that appear to be some kind of ancient anomalies. Many of the sites are situated near ancient water flows and soil erosion seems to be responsible for exposing the otherwise buried circular features. An example of an explosion crater is also included for comparison purposes. The circular features in the tour do not appear to be caused by modern testing due to the fact that water seems to be responsible for exposing many of them. Many are still buried and only vague outlines can be seen but they cover a very large area which indicates they may be part of an ancient metropolitan area, burial mounds or some type of ancient irrigation techniques. There are literally thousands of these features primarily in the Western states of the US. They are similar to the circular kivas of the Anasazi indians.
