I was looking at the city's aerial photo map and they got a layer for 2024 added as it had been missing for quite a while. There's also a 1951 layer that I don't remember seeing before or it had been much lower resolution.

Here's what used to be in AE Wilson park responsible for the ground contamination.
I kept getting lost browsing the map and had to switch to a modern one to figure out where I was. There used to be rail lines all over the city. There was a bridge over Wascana Creek on Retallack before they built a berm to protect the Crescents.
