Today Diane drove me north to visit the University of Arizona Biosphere 2, a giant 3+ acre terrarium. Perhaps you’ve heard of it. Eight people entered the facility in 1991 and stayed there 2 years and 20 minutes. during that time, they had no contact with the outside world. They ate what they grew and recycled everything. I’m guessing the food they ate had a head start so they wouldn’t have to wait for something to grow so they could eat.

I thought the additional 20 minutes was a little odd but after careful consideration I figured it had something to do with skepticism about how accurate the clocks were in 1993. Adding 20 minutes might have been a cushion to ensure they had indeed spent 2 years locked up.

Or, it might have been because one of the detainees had to use the facilities one more time before exiting. It could also have been because the second to last person to use the facilities used the last few strips of toilet paper and couldn’t reach the Kleenexes.

With Diane’s blessing I was allowed to take the 90-minute walking tour and learn all about Biosphere 2. By the way, after a little research, I learned that Biosphere 1 is actually planet earth. Biosphere 2 is a miniature earth because is encompasses most of the various environments found on earth.

Max was allowed to accompany me because he’s a good dog. That was true right up until the moment we got through the gate, and he saw the turkeys. Three of them. He did his best to yank my arm off and it took a while to convince him that Thanksgiving is behind us, so he had to leave the turkeys alone. Finally, he saw something else move and we detached from the turkeys to follow the RED arrows.

I took a lot of photos after Max decided we were OK, and he didn’t need to protect me from anything. He was, however, very curious about everything. I mean that literally. He is curious about everything and what he was seeing was totally foreign to him.

The walking tour is accompanied by an app you download to your phone that leads you to 23 locations throughout the complex. At each stop you can watch a video on your phone of someone explaining what you’re looking at. Pretty cool. It worked just fine until I missed a turn somewhere and missed #7 so had to go back and find it. That involved going down 3 levels of stairs then finally asking a handy docent where #7 was. He looked at me, leaned to his left a little and point over my shoulder at the #7 hanging in the window behind me.

Apparently I missed #1, too.

Max paused here and I’m sure he was thinking, “that’s a lot of stairs.” But, he skipped the ramp and dragged me to the bottom.

Proof of life. Made it in one piece.

That tall portion of the structure is the library that was reportedly not used a lot because getting to it involved lots of stairs like those below.

The skylight in the center is the top of the library from the inside. I think I would not have gone up there very often, either.

Next is one of the three sections where the atmosphere is controlled so they can study how water flows through soil – like how much water hits the ground and how much of it makes it to the bottom of the hill.

This tree apparently fell down, broke it’s hip and was doomed to use crutches for the rest of its life.

Finally got back outside.

This dome structure is called the “Lung” of the facility. I’s purpose is to ensure the air pressure of the enclosed buildings is maintained as the air heats and cools. Had the lung not been included, the hot air inside would have caused the big buildings to explode. That’s a lot of glass that would have littered the dessert. There’re roughly a bazillion glass panels in this place. It’s true. I’m sure I heard that on one of the videos I watched. Amazing.

Inside the next structure are a stunning variety of trees and plants.

There’s even an ocean with a coral reef. Sadly, we learned, the reef did not survive but it served it’s purpose to allow people to study the effects of various temps of ocean water.

Some of the trees in the rain forest section are 90 feet tall. This is a big terrarium.

Heading for the exit.

Back up the stairs makes a full circle.

Another aspect of the facility is the many casitas they built to accommodate scientists who come to study. I believe I heard that the casitas had 3 to 5 bedrooms for a total of 200. They are very nice, too. They won’t let riffraff wander through them. Seems like they could probably make a few bucks on the side if they rented them out to common folks.

Somewhere not far down the road to home we stopped for lunch. When I did a search for a likely location, Max spied the Grain River Asian Bistro so that’s where we went. I think it was a lucky call on his part because it just happened to be the first one on the map and we were hungry. How handy.

While waiting he thought maybe he could sit at the table with Mom.

I convinced him that dogs eat while standing on the floor. When I told him I’d order some chicken for him, he readily agreed.

Thanks, Dad
