Biosphere II

Monday we took a trip to the visitor’s center in Tucson, specifically to pick up a coupon book for attractions in the area.   Great deal…$20 for the book which contain several discounts and “two for one” deals.   We then ended up taking a walking tour of the old area of Tucson and had a phenomenal lunch at “The Little One”.    One of the menu items was to let the kitchen decide what you’ll get, so we decided split that.  Three items, and each one was amazingly good.  Total bill less the $18 including drinks.  We’ll be back!


So, today (Tuesday) we decided to visit Biosphere II, just up the road a bit from where we’re currently staying.   I did a bit of reading, and the place is not without controversy, but the science and engineering that went into building the place is, without doubt, some of the best on earth, or in space.   When it was a sealed facility (some of it is still partially sealed, but most is not), it had less of an atmosphere loss then the International Space Station!   We can both highly recommend a visit, and if you get lucky, you’ll have a gentleman named Lynn give you the tour….our 1 hour tour lasted almost 2 full hours and Lynn was very interesting!


Although probably best known for the group of 8 scientist which spent two full years in the biosphere (or the failed second attempt which was cut short due to strife), the entire complex is currently owned by the University of Arizonia and is still a huge science and research facility.  A lot of the science and discoveries made over the years was given to NASA, at no cost.


The complex is made up of 5 distinct bio zones.


The Ocean, currently being redone to duplicate the Gulf of California


Betsy in the steamy Rainforest


Some very cool plants!


The Arid area


High desert




Some of the 6,500 Windows, 91 feet tall



One of the two “lungs” on site for air circulation.



All in all, a very interesting visit, and much better than we expected!

    We were there a few years ago – I believe Columbia University owned/ran it at that time; they ran a hotel on the campus, run as a Monsanto corporate retreat. Anyway, fascinating and we’re glad to see it is still in existence. Will you go to the Amerind Foundation while you’re down there? It’s in Dragoon…
