no they arent, its where you go. And damn, i guess they just hit their average early. People go to Louise for the same reason Texans go to Sun Valley or Summit County, its a social status and tradition. "I just spent the weekend at Lake Louise" sounds a lot more impressive to your golf buddies who know jack shit about skiing, than "I just spent the weekend skiing blower in Revelstoke."
Places worth visiting in the canadian rockies
Sunshine Village - 350in a year, also gnarly as fuck
Fernie - 350-375 a year, gnarlier
Kicking horse - 275-300 a year, less snow, imo even gnarlier
Castle Mountain - 450 a year, not as gnar, usually deeper
places that are kind of in the Canadian Rockies
Revelstoke 450-500 a year, you will jizz
Whitewater - 475 a year, no Revy but still jizz worthy
And if Lake Louise has a good base its a great place, just don't go there expecting anything other than groomers
