Analysing terrain data
1 - 2
The exposure grade does not take into account objective hazards (stone fall, seracs, etc) 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.
Park at the Neffs Canyon trailhead in Mount Olympus Cove.
From here follow the road up into Neffs Canyon.
At the first junction head to the right up into N Fork of Neff's.
This trail is narrow and winds through the tight trees as it heads to the S.
The area is very brushy and can be a rough go in low snow years when conditions are thin.
Persevere the path, and you'll find yourself at the base of the Memorial Couloirs for some excellent steep and tight chute skiing.
There are 5 main Memorial Couloirs.
#1 is the uppermost that runs off the S summit of Olympus and the others follow to the N.
