I have some additional concerns to the ones I have already posted.
How cold will it be riding lifts at 11,000 + ft in Dec. Jan. and Feb. in mountains that are this far north? Most western Canada resorts top out at around 7,000 ft with a few at 8,000 ft. The only people skiing at 11,000 ft in Canada are riding in a warm helicopter. Should be great in July and August.
Most master plans are overly optimistic pie in the sky because it is easier to shrink a plan down the road than it is to expand the plan, this one is probably not an exception. The plan calls for 23 lifts at build out with 5,500 beds. IMO 5,500 beds will not supply enough skiers to justify the cost of building and operating 23 lifts.
The original driving force behind Jumbo is Oberto Orberti an architect with no ski industry experience. 10 years in to the Jumbo project he realized that it wasn't going to happen any time soon so he shifted to developing Kicking Horse Mountain Resort with a Dutch construction company investor, also with no ski industry experience, and set up a 3900 vertical foot gondola with no mid terminal. This has caused early season problems when there is no snow at the base but lots up top that can't be accessed. KHMR has been operating for 12 years without making a profit and was sold this year to Resorts of the Canadian Rockies, presumably at a bargain price.
