Man-made Structures - Other to Explore in Pinal County
Biosphere 2Biosphere 2 is an American Earth system science research facility located in Oracle, Arizona. Its mission is to serve as a center for research, outreach, teaching, and lifelong learning about Earth, its living systems, and its place in the universe. It is a 3.14-acre structure originally built to be an artificial, materially closed ecological system, or vivarium. It remains the largest closed ecological system ever created.

One of the buildings is shaped like a flying saucer and the other three are as if spheres were joined together, looking like huge concrete caterpillars.
