Couloir Pk

(5 routes)

After Hugh Wright and Jim Murphy abandoned their attempt in 1912, to make the first ascent of Mt
Arrowsmith, Couloir wasn’t climbed until 1934. There are several options from Lawrence River.
The Couloir is the classic route to the summit of Couloir Peak, pioneered by the redoubtable Stan
Conway and Tom Newth and the scene of their legendary 2500-foot fall during a storm on the
descent. After their successful climb, an avalanche knocked Tom off his feet, he collided with Stan and
they tumbled down the couloir in a long series of arcs, alternately airborne, then pounding into the ice
as the rope between them became taught and reined in their flight. Eventually the rope coiled around
Tom and the arcing stopped. One last flight saw them clear rocks at the bottom of the couloir before
hitting the névé and rolling to a stop millimetres from the edge of a crevasse. Both were injured, with
Stan having to be evacuated by horse. Despite this, Tom was able to show up for work the next day
and the incident was glossed over – although it was more than 20 years before the route was repeated.

Follow the top of the moraine wall above the Lawrence Glacier and from here climb a solid
rock ridge to the crest. Traverse south, climbing into a gap with a steep bluff on the north side,
then continue to the summit


From a shingle slope, follow the creek draining the north side of Mt Arrowsmith and climb
to the upper basin. From here traverse Pt 2474 metres and reach the crest of the range slightly
north of Cameron Col.


Start up the glacier where the moraine wall has been breached, then follow scree and snow to
the high Twins–Couloir basin. Climb a steep wall of rock to reach the final ridge and summit.

South Gullies 2+
Take one of the two prominent gullies left of the main couloir which lead to a small plateau on the Lawrence divide. From here, follow reasonably angled rock for the last 200 metres to the summit, or follow a snow-filled gully left of the rock.
Geoff Harrow, Barry Owen, February 1950
SR South Ridge
Climb the ridge south of the peak, which leads directly to the summit, starting either on rock or up an ice gully.
Arthur Lees, Ambrose Banfield, April 1938
TG The Couloir 3
Follow the Cameron Glacier to the base of the prominent snow couloir cutting the south-east face of the peak. The lower section contains the crux, a steep, two-metre ice wall, after which the route lays back to about 45 degrees and ends about 30 metres from the summit ridge. From here, cross left under the buttress into a short, steep, icy gully then follow good ice for the last 10 metres to the summit ridge.

The Big D 16
Direct route on East Face of Couloir Peak (2642m) From Cameron Hut, allow 5h for the approach, 7h for the climb, and 7h for the descent back to the hut. Approach – Up Cameron Glacier past icefall to glacier confluence (1700m). Turn left, ascend to 1950m. Then take a right up a steep (50 degree) ice slope to eventually arrive at the base of a prominent corner directly below the summit (2300m). Start 10m right of the main corner. Pitch 1 (40m, 16) – up crack until under roof (20m). Turn the roof by traversing left onto the face (crux). Ascend slabs to belay ledge. Good rock. Pitch 2 (15m, 15) – up corner to belay ledge Pitch 3 (40m, 14) - traverse right out of crack and around arête for 10m. Then up a series of ledges on quality rock Pitch 4 (40m, 12) – follow cracks up to large ledge Pitch 5 (35m, 10) – down right into gravel, then ascend loose easy ledges arriving at a red corner. Pitch 6 (20m, 12) – right and up to top ledge up crumbly, difficult to protect, rock. Scary pitch. Pitch 7 (30m, 15) - traverse left past red corner then up fissure past detached pillar and around corner Pitch 8 (45m, 12) – traverse 10m left then directly up. Follow a series of cracks to wide ledge. Pitch 9 (100m, 10) – Easy scramble up and right. Simul-climb this pitch taking care rope drag doesn’t drop loose rock on partner below. Pitch 10 (100m, 10) – Easy scramble. From the summit ridge it is a further 100m traverse past af gendarme to the summit (2642m). Descent – continue traversing 100m along summit ridge to the SW until at small col above a steep snow/ice couloir on the TL. Descend this steep couloir at first (a rap may be required) for 250m (vertical) to a wide snowfield. Continue along this 600m to the right staying to the west of the ridge on easy ground, crossing point 2474, and eventually arriving at Cameron Col (2427m). Cross the Col and traverse a further 200m due south across the glacier and then carefully turn to descend 700m of steep snow/ice to arrive back at the glacier confluence (1700m).
