Archives are elusive and beautiful things. We thought we had viewed all of the documents related to planting on campus when Sonya, the University Archivist, and I found note of a 1936 “Trees + Shrubs” plan filed with some unrelated items. Upon pulling the file we found this incredible, 3’x7′ campus-wide plan of the University’s landscaping. Here we found verification of the commemorative and alumni trees, as well as the first clear species call-out on the rows of pin oaks.
The 1936 date confirms much of what we deduced on our visit to the tree-ring laboratory last week. While the specific planting date of each one of these incredible oaks may never be known exactly, we are moving toward confidence that the trees are ~80 years old.
