Analysing terrain data
The exposure grade does not take into account objective hazards (stone fall, seracs…) but only the consequences of the skier falling.
Low Exposure (E1): Exposure is limited to that of the slope itself. Getting hurt is still likely if the slope is steep and/or the snow is hard.
Medium Exposure (E2): As well as the slope itself, there are some obstacles (such as rock outcrops) which could aggravate injury.
High Exposure (E3): In case of a fall, death is highly likely.
Extreme Exposure (E4): In case of a fall, the skier faces certain death.
The Tri-Chutes are a lovely set of three large gullies high up in the White Pine Drainage.
They are some of the longest open runs in the Wasatch with a continuous and uninterrupted pitch.
They do however see a lot of wind since they are high on the ridge and west facing.
They can be wind scoured.
In the spring they can be a great corn snow run! To approach, park at White Pine trailhead on the south side of Little Cottonwood Canyon.
From here take the trail that follows a road grade up the switchbacks and into the upper basin.
Stay on the left (E) side of the valley and climb past Birthday Chutes and then you'll pass underneath the Tri-chutes.
Aim for the saddle to the SW of the chutes.
From this saddle you can safely gain the ridge and climb up to the top of American Fork Twin Peaks where the chutes begin.
