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.
Starting at the summit of the King, Brain Damage is the obvious steep couloir to the right of a north-facing rocky buttress.
At 800 vertical feet from the summit to the bottom of the upper basin, Brain Damage is relentless.
The couloir starts steep.
Watch for cornices at the top, especially just to the right of the center.
The easiest entry is on the left, but is a no-fall zone at it hangs above the rocky buttress mentioned above.
A few turns in, this chute narrows down to about a ski-length wide.
Control your speed through here as it steepens up below over a rocky band.
Work the sides of the chute (which are not as prominent below the upper choke point) to avoid a sloping rocky outcropping that often plagues this otherwise spectacular couloir early season.
Below the chute widens a little for some steep, consistent north-facing snow.
The snow here can often be creamy and soft when the rest of the ski area is baked or slushy.
Watch for avalanche debris at the base of this chute.
