Driving Highway 210 Little Cottonwood road. Go past the main parking area for Alta Ski Resort (Goldminers daughter) and park on the side of Highway closest to the Shallow Shaft restaurant (8,600ft). Approach Located on the back side (north) of Mount Superior, the approach is moderate. From the Little Cottonwood Canyon road, skin up pole line pass.  When you reach the pass head left (west) along the ridge, past Cardiff Peak.  Keep going past Cardiff peak along the ridge. The fastest way to access Cardiac Ridge is to follow the ridge past Cardiff peak and  Just before the next climb up a short knoll on the ridge, you want to stop and remove your skins and transition to ski mode.  The ridge past here gets a technical and there will be no easy way off once you pass it. Now ski down slightly into Cardiff basin and in the same direction you were skinning (west) around this shoulder.  Ski down into Mill-D drainage.  You'll be able to see Cardiac Ridge and head directly for it. When you get to the base of The Thunderstruck couloir transitions from skinning to boot packing and make your way directly up it. The Lightning Bolt approach Is the same as Thunderstruck.  Only when you reach the base of the chute you have a choice of booting directly up it, or boot packing up Thunderstruck couloir and skiing down from the top.  The Wyatt Couloir approach - Boot Pack straight up it.
