I really enjoyed reading through this and I think it'll be blast to run!
I know it was stated earlier but I do agree with I feel there would be alot of back and forward (flipping pages/pamphlet) while running to get the location and hazards right. I would likely build myself a little cheat sheet before running to avoid this issue and have to try and cover all the stacked environmental effects on the fly.
Minor - probably more personal quibble: I found the NPC illustrations actually took me away from the module itself as for me, they're very clearly contemporary aircraft (contemporary used lightly for Marie).

I've moved the map (and other things) around so the back-and-forth flipping is no longer an issue! Appreciate the note about the NPC portraits; one thing that made the jam a fun challenge on the whole were the many decisions around the interpretation of Time, its scale and scope, what's ancient vs contemporary. Your experience, personal or not, is an outcome I wasn't expecting, so definitely thanks for sharing it.
