I am here to report we finally made it inside Biosphere 2, the world-renowned, self-enclosed science station run by the University of Arizona near Tucson. You may recall that last year, my son and I saw the station, but only from the outside because we didn’t have time to wait for a tour. (We had to catch a plane home.)
On our recent trip, we allowed ourselves plenty of time and were able to buy tickets for a general tour. The day was rainy, so many others had the same idea, and the place was packed with other science-nerd people who wanted tours.
Touring the rainforest.
We arrived too late for a tour of the “ocean,” however, which saddened my Sea Grant-y heart. By 10 a.m., only one ocean ticket remained, and there were three of us. I was tempted to mutiny and claim the last ticket, but I don’t think Russ and my son would have enjoyed that move on my part.
Several different biomes are featured in the station. Our tour first led us to the rainforest. When my son and I saw the rainforest building last year, plants were plastered against the windows, even several stories up – almost bursting the glass. Scientists must have been getting worried because they started a drought study on the rainforest. The plants now are much less dense, and a little sad and brown, but I suppose they had to do something to contain them.
Although we weren’t able to get a tour of the ocean “beach,” we did see it from above. As the sign says, it’s one of the largest research oceans, although it’s in bad shape. Acidification has killed the coral in it, and last time we visited, algae were creating problems.
The ocean.
I love nature, but the coolest part of the tour for me was seeing one of the building’s “lungs.” The station was built to see if it could be possible to construct a life-sustaining enclosed environment on Mars, or some other such planet. The station’s two lungs performed the function of equalizing air pressure between the inside and outside of the station. They worked so well that only one of the lungs was needed, not both.
We ducked through some small openings and walked down long cement corridors to get to the center of the South Lung. A water reservoir stands in the middle of the lung, covered by a hugely heavy metal plate that’s attached to a rubber membrane from the ceiling, which our tour guide said is made from the same rubber as Zodiac boats. The plate falls or rises in response to pressure changes. Legs on the bottom of the plate keep it from crashing into the floor as pressure drops. The plate is reminiscent of a flying saucer. The lung looks like a great setting for a creepy fiction story. Hmmmmm.
The peek inside Biosphere 2 was fascinating and I recommend it.

I recently had the privilege of reading a poem for Northland College’s “Writer’s Read” 10th anniversary event in Ashland, Wisconsin. This is the second time my work has been chosen for this contest. The first time was 
We were not offered cash for our winnings, rather the comradery of other writers, instant fame the reading provides (ha ha), and some great food! They fed us Mediterranean-style dishes prepared by a student chef, including homemade marshmallows cooked over a fireplace. Okay, the marshmallows probably weren’t Mediterranean, but they were still impressive on ‘smores.
Russ and I visited a northern Minnesota lake last weekend. Spent part of an afternoon snowshoeing on a frozen lake. The morning’s hoarfrost floated down from the trees, looking like snow magically falling from a clear blue sky.
I meandered just a bit south to Carlton, Minn., to attend an Ojibwe pow wow for work. More like I white-knuckled it on the drive due to a snowstorm.
I thought I’d share a few of the more interesting points with you. The first is that a pow wow dancer’s clothing is called “regalia,” not a costume. The info sheet says, “Costumes are worn to present yourself as something you are not.”
