West Couloir

From the basin immediately south of the bend in the Lawrence Glacier, follow the small glacier
that leads to the east-trending couloir that runs towards the summit of Tower Peak. Climb the
couloir to a notch in a prominent rib. From here, traverse along and slightly down the ridge
before heading up diagonally across the face on ribs of sound rock interspersed with friable sections.
Gain the summit ridge and climb straightforward rock to the summit pinnacles.
