The company that flies to Waddington is Glacier Air out of Squamish. There is an airstrip about a mile north of town. I used them about 7 years ago. The cost per person was roughly $450. There were three of us that flew into the Tiedaman Glacier in April to climb The Wadd, Combatant, Tiedeman, and do a ton of skiing. The pilot flew a Cessna 210, if my memory serves me right. It took one trip in and two trips out because the glacier was a bit sloppy. On the way out we had a very interesting flight as the engine sputtered because we were running on empty. The pilot didn't take in account that he would have to fly half of the gear and group down to a hard runway at Scar Creek and go back for the other person and gear. Other than that we had a great climbing trip. We climb everything we intended on to during the trip, weather was great.
