On its own the NW Couloir is a fun distraction if hanging out in the meadows and one just wants a nice 3rd or 4th class walk up. Views of the Cathedral group are stellar. Winter can be hit or miss. Have boarded it with absolutely heavenly pow while at other times it has been boiler plate from summit to meadow.
Climbed the Northwest Couloir in January 2017. Dropped our skis at the base of the Couloir as it was too rocky to ski. Summited right at sunset and the alpenglow on the grand and Middle Teton was one of the most beautiful things I have ever seen. There was a lot of wind blown ice on the summit and the Couloir was quite icy as well. The ski down from the base of the Couloir was icy as well, but we reached good powder further down the south fork. I have climbed the route in the summer several times before and while it was beautiful then, the winter views were far more spectacular. I highly recommend a winter ascent to anyone. If you do it in the winter make sure to bring an ice axe and crampons as the ridge beneath the Couloir had a steep and icy slope beneath it.

I climbed the South Teton solo via the Northwest Couloir back in June. I started from the car at about 2 AM and was on the summit by 9 AM. The clouds had not burned off yet and were streaming off the Cathedral group in beauteful ways. The climb was covered in snow from Garnet Canyon to the top, and the wind was quite intense in some places. I was the only person on the mountain that day which was kinda cool.
Fun day with Julie, Tony. Mark climbed everything in sight and Teak and Tami climbed the Middle. Great day with great friends.
Climbed the Middle Teton right after the South Teton.
Didn't have it in me to double the Middle and South, but I came back a week after climbing the SW Couloir on the Middle to climb the NW Couloir here on the South. Great route and being late season, I was able to avoid snow the entire way.
Ok, I'll get this log started. I do not remember the exact date I climbed this route, though I do remember lots of snow and wind.
