Polar Star Couloir Map

In the far-off and otherworldly landscape of the Baffin fiord-lands, there is perhaps the highest concentration of incredibly long and skiable couloirs to be found anywhere on the planet. Amongst these formidable granite walls split by endless couloirs, Polar Star stands out for how utterly compelling and mesmerising it is to look at. Laser cut into Polar Sun Spire it slices cleanly though one of the world’s very largest sea cliffs. The quality of the skiing is also impeccable; north facing, cold chalky snow or compact powder is virtually guaranteed and you'll find 1,100m of 40-50 degree skiing in a couloir which is never too narrow to make fluid turns. The top 300 meters are quite steep and snow doesn’t always stick to the permanent ice underneath. After the top section the skiing is relatively straightforward while the ambiance is anything but ordinary. No superlative adjectives can do justice to the colossal scale of both the towering spire and its splitter couloir.


Polar Star Couloir was first skied (and thus named) by the visionary and exploratory steep skier Andrew Maclean. It has since become a global classic, yet the term ‘classic’ is something of a misnomer. It is in a remote and inhospitable arctic wilderness and therefore sees very little traffic. The only way to ski it is to commit to a full expedition into the Baffin fiords, which is both expensive and requiring of considerable logistical planning. Baffin is not a well-known ski destination and it really defies logic that world class alpine skiing should indeed take place at all on the world’s 5th largest island. With a population of 15,000 and only a handful of ski expeditions arriving every few years it will remain indefinitely a remote wilderness.
