I think "H.I." means height of instrument. It's the ground elevation plus the height of the camera lens above it. It's a surveying term, an important measurement in running elevation profiles.

That makes more sense than what I thought. Thanks for the elucidation.
It's interesting how each photographer annotated their photos.
Now I'm wondering what "SUP.NO.1." means on the Olallie Butte photo? And the number 284752 on the lower right corner?
This talk looks interesting:
Wednesday Oct. 19 6:30-7:30 p.m. "Fire Lookouts of Oregon" book talk with author Cheryl Hill at the Museum of the Oregon Territory in Oregon City, 211 Tumwater Dr.
Maybe she knows lookout language!
