Alta cannot have it both ways with One Wasatch. Snowboarding is not currently allowed at Alta. For One Wasatch to be a completed, Alta will have to permit snowboarding.
Perhaps One Wasatch is at best a thinly veiled ploy for Alta to permit snowboarding and save face with its hard-core skier base. Otherwise, One Wasatch will have to be renamed One-Half Wasatch. Without snowboarding at Alta, One Wasatch will only be able to cater to one half of the snow riding population.
