Just playing around with numbers for fun, but you're probably seeing the peaks around Kananaskis and South of it? (Straight shot it's it's ~150 km away, Banff is like 194 km). Pretty sure Goat Mt beside Yamnushka isn't visible even at 2300 m, but Mt. Townsend should sorta be at 2780m. Lots of mountains south of that would be visible.

I took a look for fun at heywhatsthat.com (site for radio comms and earth curviture) and the red peaks on the attached map screenshot are the ones that should be able to see line of sight from where you live.

It's a cool site to play with. You make a panorama from a point you want (your town) and then click on the map to see what's line-of-sight for radio comms. You can even turn on the earth curviture in the profile to see how it would look as a side shot.
