I think the big cluster you're looking at (sort of an arrow pointing to the NE) is Edmonton, then you can go SSW through Red Deer to Calgary. A few hundred miles east of Red Deer is Saskatoon, and SE of that is Regina (rhymes with ...).
I think Edmonchuk is a bit more west than what I’m seeing. I think Edmonton/RedDeer/Calgary/etc is the 2 dots with a sharp vertical line even west of SLC. The spot I am referring to is about the same latitude as Edmonton but even a bit east of Denver. It’s a bit diffuse but about the size of Chicago. weird.
