This line lies directly below Upper Slot. It makes a logical start to that climb because of its position. Scramble up to a bulge with a large u shaped groove above. Place a large cam to the right of the bulge and muscle/ scratch your way up on to the face above the bulge. Ascend the groove past two old bolts by thin stems and crimps. It is possible to protect the final move out of the groove on to the ledge below Upper slot by placing an ok RP on the right side.
2 old 1/4 bolts, large cam for the start and an RP for the top out.
