L to R R to L Alpha
Start by climbing over, squeezing around, or otherwise surpassing the tree at the start, and climb up a dirty dihedral to the overhang. The crux comes with a traverse to the right following beneath the overhang. Top out at a three bolt anchor.
From the Middlefork trail, pass several routes on the Lower Lunchbox, then take the steep descent trail up and stay to the right and arrive at the Upper Lunchbox. Look for the obvious tree growing out of the wall, route starts there and follows the overhang right. Three bolt anchor at the top.
Lead: Small/medium gear, slings. A few tricky placements, but it's very protectable.
