Description

Grunge Couloir is a steep snow chute on the NE end of Timpanogos. It's a great, direct way to reach the north summit of Timp and more aesthetic than it's neighbor, the Cold Fusion Couloir.

The couloir is sustained in the 40-50 degree range with a short crux near the top that supposedly reaches 62 degrees.

A helmet is definitely necessary as the couloir is known to spew rocks (typically a large runnel can be seen running down the center of the chute), so keep your ears and eyes open.

As of May of 2014 there are two rap stations in the couloir, presumably used for ski descents. One is about mid-way up, the other at the top just above the cornices.

As with any snow climb, make sure you're checking snow conditions before committing to the couloir, which would be a death trap if it slid with you in it.

There are a few descent possibilities. You can descend the NW ridge down to a dirt road and hike it in back to your car, or, as a friend of mine has noted, you can simply glissade down Cold Fusion Couloir (assuming it has snow in it) which took him a reported 20 min. OR, you can treat yourself to an amazing day and continue along the summit ridge to tag the main summit (bonus points for ticking the south summit as well!).

Location

Reach the couloir via the Timpooneke trailhead in American Fork Canyon. Head up into the Wooly Hole Cirque and contour to to the right and up a broad face to reach the couloir which is split into two forks.

Protection

I've heard reports that ice can form in the couloir. My partner and I took one technical ice tool and a mountaineering ax, though we didn't end up using the ice tool. With firmer snow than we had, or if ice is encountered, I could see a tool coming in very handy. Crampons a must.

Cold Fusion is the popular main season ski descent as it is lower angle, wider, and generally more friendly. The grunge is usually saved for the spring when the snowpack has firmed up, and skiing conditions can be considered safe at the steep 50+ degree upper slope. Either way i'm sure it's a fun climb for some, and a great descent for others! Jun 4, 2014

Is it classic because of its inclusion in the book "Chuting Gallery," or because it actually is skied frequently? While I myself am not a skier, I thought the Grunge had a reputation for being somewhat dangerous. I don't know anyone offhand that's skied it (unless you have), while a lot of my friends have climbed it. It seems the far more popular descent is Cold Fusion.

But yes, either way a valid point. Beware of the possibility of skiers. May 31, 2014

Beware this is one of the classic couloirs in the wasatch for skiing. If you see skiers ahead of you it would be wise to either catch up to them or bail as they're going to send debris onto your during their descent. May 28, 2014
