To approach, park at White Pine trailhead on the south side of Little Cottonwood Canyon. From here take the trail that follows a road grade up the switchbacks and into the upper basin. Stay on the left (E) side of the valley and climb past Birthday Chutes and then you'll pass underneath the Tri-chutes. Aim for the saddle to the SW of the chutes. From this saddle you can safely gain the ridge and climb up to the top of American Fork Twin Peaks where the chutes begin.
