Here’s another one I found. This was donated by someone in Ontario, and it’s in an old backup from 2013. Unfortunately, I didn’t put who donated it in the filename and it’s been lost to time. So thanks, whoever did it. Drop me a line if you want and I’ll give you attribution. Note that there are two pages.
In any case, I haven’t seen diagrams like this a lot. It’s kind of cool if you’re a diagram person (which I’m not).
And here’s the link: https://wordpress.forensicpath.us/wp-content/uploads/2026/10/ontario_layered_dissection_diagram.pdf
