Harrington Couloir

A moderate snow/ice climb up the 3rd prominent couloir from the left as seen on the approach. Max angle of ~50 degrees near the top. From the top of the couloir, walk north for 10 minutes across the summit plateau to the final 20' 3rd class rock scramble to the summit.

There are 4 prominent couloirs on the North Face of Thompson. A cluster of 3 couloirs sits on the left side of the face, and the Harrington Couloir is the rightmost of these 3.

Depending on conditions, snow pickets, ice screws, and/or some rock protection could come in handy.
