Expedition

(snow shifting) (panting) This is hard work. We haven't even started yet. (ominous music) We need to reach the top of this snow slick before we can get a look at the route ahead and the summit we're aiming for. (sighing) Watch out! A bit of sliding snow. Nearly there. Amazing! (vibrant music) Yes! For the first time, I can see all we're taking on. And it's actually flipping massive. From here, we have a vertical kilometer to climb if we're to reach our goal. The snow is giving way to more technically demanding rock. There'll be no chance of sleet until we get back down, and no one knows how long that will take.
