A long and slightly complex line, very unique for the area. Activator Gully faces east, making it a good early morning run in the spring. This also means it can be baked out very quickly on a hot day. The exit to this run burns out in late spring, so March / early-mid April are the best time to attempt this line. Reach the summit of Mount Clay and drop in to the Great Gulf, a short hanging snowfield leads to a left trending ramp. Make turns down this exposed ramp, which empties out into a wide, low angle chute. Ski this all the way to the bottom, until the line is closed off by a small cliff. Bushwack to skiers right and exit the gully, trending towards Spaulding Lake. Skin back towards Spaulding Lake and reconnect with the bottom of Airplane Gully for the exit.
