The Waldo Chute is named from the "Where's Waldo" Character because the run is hard to find, and is sometimes confused with the Whipple Couloir. To access the Waldo, park at the S curve in Big Cottonwood Canyon at mile marker 4.3. From here walk up the road and onto the trail to the N of the road. There is a summer trail that heads up away from the road and into a thick canyon. The summer trail will disappear, but keep thrashing your way up the canyon keeping an eye on the left side for an open slope that you'll start skinning up. It doesn't look like much, but persevere as it will open up and you'll enter the chute.
