Hiking Models/Mt Rainier

Looks like I'll be heading to Mt. Rainier this weekend after all to scout out a location for the "ice" segment of the elements themed photo shoot we're planning. The spot will need to be relatively accessible for the equipment I'll be carrying and easy to hike to for the model. I don't think I'd feel right asking a model to hike several vertical meters in a cocktail dress and heels. I think I know just the right location but I also know a few models that would do it.
