A steep, corniced chute with a mandatory double air.


Analysing terrain data









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.

In case of a fall, death is highly likely.


Krakatoa is one of a few lines accessible from a short bootpack up onto the cliffs at the top of the Blackcomb Glacier.

Once you've hiked up from Showcase T-Bar to the top of the glacier, follow the wind lip all the way to the cliffs on the other side, uphill of the backcountry gate.

It's a harder bootpack than the one you will have just done but the lines up here are totally worth it if you're looking for something steep, some fresh snow in the days following a powder day or just feel like working on your glutes.

Once you've made the bootpack up, traverse around some rocks and up to a chute.

Hike around the back of the rock ridge to the top where you'll see a fairly sizable cornice.

Be careful! Before you drop in, take a breath and admire the awesome views from up there! Drop in off the cornice onto a wide slab of snow before your first air, which promptly leads you to your second.

These airs can be anywhere from 2 to 10 meters depending on the snow that year.

After the second air be aware of traverse lines made from people accessing the backcountry gate.

The line drops you back into Blackcomb Glacier, and from there it's worth staying right and following Husume Flank down. You finish on Blackcomb Glacier so take crevasse rescue kit in your group.

A minimum would be 30m ropes x 2, a long sling, 3 screwgate karabiners, prussiks and an ice screw.
