Whistler British Columbia Climbing

Howdy Folks!

I'm a couple of weeks from heading out to the Whistler / Blackcomb area of British Columbia for some snowboarding and am contemplating taking along my climbing rig to boot. There's so much talk about old growth tours and zip-line tours and treetop tours in the area it has aroused my curiosity. I am wondering if anyone has climbed in the area, or lives in this area and can give a heads up to where may be the best climbing, particularly the Lost Lake or Fitzsimmons Creek areas directly adjacent to town / ski area.

Thanks!
Eric
