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.
This narrow, no-turns couloir is not for the faint of heart.
This is the most challenging run off the summit of the King, probably in all of Southback.
It is also front and center on the King and can be seen from the Campbell Basin Restaurant.
Anyone willing to straighline Pinball should check the condition of the snow at the base.
There are often chunks of frozen debris that you will most likely hit at high speed.
This couloir is too narrow to make turns and must be straightlined.
At 800 vertical feet and 50 degrees, this chute provides plenty of time to gain big velocity.
The upper portion of Pinball is defined on the right by the north-facing buttress that splits the north side of the King.
On the left is a less well-defined face that is often rocky abutting the couloir with a rocky edge.
Pinball starts at the summit of the King, and runs nearly straight down to the bottom.
A bit of rock juts out from the right part way down and can be deceiving.
If you hit this you will pinball down the remaining narrow chute.
