The Rockies...so nice...
A massive area, with large distances between decent bouldering areas. Worth visiting for the sport, alpine, ice and mixed climbing. Several good guides available for these - Google Bow Valley or Rockies Climbing and you can find 'em. Add the Ghost wilderness area to that.
Bouldering is the red-headed step-child of the more popular forms of climbing here. There is potential, but you need to be committed to find it.
