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 Naya Nuki Headwall is a real treat when it fills in.
This area has multiple entrances directly above the middle section of The Great One.
The upper half is about 40 degrees but very wide and open.
Skiing down is mostly straightforward and fall line, although there may be some rocks poking out of the snow to steer around.
Be certain of avalanche conditions when attempting this line as it wind loads often and is at that perfect pitch to slide.
The Naya Nuki Headwall has almost a directly east aspect and the full line is about 1200 feet.
To get to Naya Nuki, park at the Fairy Lake trailhead, about 1.5 miles from the highway.
Head up the (closed in winter) Fairy Lake Road, and take the summer trail to Sacajawea.
Naya Nuki is the South peak of Sacajawea.
The headwall will be about 50 yards before The Great One.
Be wary of the cornices as you walk up to peer down this face.
Once down, trend left, making your way to Fairy Lake and back to Fairy Lake rd.
