I found these new aerials in a box of unsorted slides that were inherited from a previous archivist. They’re just beautiful shots, crisp and clean, and the campus looks so immaculate that I suspect they must have been taken near commencement time. If you look closely around the edges you can see where things have changed–the middle tends to stay more or less the same for longer periods. They’re dated 1985. I’m not confident about that but I do think it’s pretty close:
Bonus: 
Can’t see the cars well enough to identify them. But Herring Hall was 1984 and it is there.
They are lovely, but I see only two aerials.
WordPress vanished one. I’ll see if I can fix it.
The Mechanical Engineering Building was completed in 1985, and it is on one of the pictures.
And George R. Brown is missing, so that puts an upper limit on it of ’90-’91, depending on when construction started.
Bonner is still there, 45/60/90 is in place, the yews are up, MOB practice field Is still there, yep, feels like 85 or so.
Yews? Or Italian cypress? I don’t have enough resolution to be sure, but I think the latter. The yews were in pretty bad shape, especially near Rayzor, by the time they were removed and were not so slender.
If I recall correctly, that change happened after George Rupp became president in July.
They Ley Student Center (addition) opened in ’86, and it does not appear to be present.
