The name says it all. As serene and soothing as a Mud Honey concert
in a hurricane. The Grunge Couloir is mainly considered a spring/summer
alpine climb, but it makes a pretty good ski descent as well.
The sides are lined with towering, rotting rock walls that send
down a constant barrage of buzzing missiles. Most of these find
their way into a five foot wide semipermanent runnel that divides
the already narrow chute from top to bottom like a bowl of old
pudding. Between the angle (over 60° at the top), the half-buried
rocks and the runnel, there are enough objective hazards to keep
even the most attention deficit disordered grunge rockers
The Grunge Couloir is located on the north side of the North
Peak of Mt. Timpanogos and is best approached via Highway 92
heading toward American Fork Canyon. From the Timpanogos Caves
National Monument parking area, continue approximately five to
eight miles up canyon until you reach a T in the road. Take the
South Fork road and follow the signs to the Timpoonoke Trailhead.
Pass through a pay station and continue bearing right as you
continue up the road, eventually pulling out at an unmarked but
developed parking area on your left. Gear up and follow the trail
for about 10 minutes to a small meadow, then follow a ridgeline
up and to your right. Follow the ridge about 2,000 to the
base of the couloir. June/July are the recommended seasons and
crampons and an ice axe are recommended.
