The UA Science: Sky School, a residential science program in multidisciplinary science, is housed at the summit of Tucson’s nearest Sky Island, in an old military base converted to an astronomical observatory. One of the buildings on site, the old enlisted barracks (it was only men up there back then), is condemned and boarded up. No one to my knowledge has been inside in a decade. It is very, very dark if you walk past it on a moonless night to set out a wildlife camera. (I sing to myself if I’m alone.)
Ten days ago, I was up at Sky School with a group of middle schoolers, and walking past the enlisted barracks in the night, we saw a light on in a downstairs window!
