Campus mystery

Okay, friends, when we started this blog, we said we would ask for help from time to time. Well, here we are!

Our Photographs Curator has been stumped by this for some time. Can you help put his mind to rest and help us identify the pyramid-like structure in this image?

This detail comes from a large panoramic shot of the “new” 10th Street Stadium in 1924 (now home to the Arboretum). On the far left you can see the south bleachers and the pyramid-like structure would be about where the present-day Radio & TV Building is located.

Brad has contacted several people over the years in hopes of receiving some help in identifying the structure but thus far has had no luck. It doesn’t show up in campus maps and he has not uncovered any other documentation about it. Anybody have any thoughts?
