This one seemed healthy, at least at the time, but producing a ton of nonviable seeds. Sort of triangulated between the Administration, Hampton & Ridenbaugh buildings.

Years ago, I was able to find one seed from a tree in Moscow on the UI campus. Sadly it was inadvertently discarded while germinating over the winter. (To be fair to my sister-in-law, she had young kids in the house and to the untrained eye it just looked like an old peanut butter jar full of dirt.)
