Yak's short east face is located high above the long routes on the SE face, well to the right of Madness.
Reach the face by hiking the climbers approach trail to the base of Yak Crack. Head right, and climb the normal descent trail for almost 500m until you break out of the trees into the meadowed bowl SE of Yak. At this point, head left through the meadow to the concave east face.
There are three or four curving dihedrals on Yak's east face. The Babicki/Menninga takes the central and longest line. The others have also been climbed over the years and feature shorter route lengths but similar climbing. Bring a couple large cams for the wideness.
High above the highway on the East Face. walk off right to descend.
Extra big cams in the 2" to 5" range.
