18 hours - The first non-stop ascent of Cerro Largo

THE FIRST NON-STOP ASCENT OF CERRO LARGO

First ascent of the north face of the Zugspitze

Chile - LOWA-PRO team athlete Robert Jasper's expedition last year took him into a sea of white: the Patagonian Ice Sheet. Together with mountain guide Jörn Heller, sports scientist Dr Andreas Thomann and outdoor photographer Klaus Fengler, who had already been part of Robert's Greenland expeditions, the rope team set off together in October 2019.

UNTOUCHED ICY LANDSCAPE

Barely explored and almost untouched ice landscapes are the measure of all things for many professional athletes. When it comes to planning the next expedition, it can't be untouched enough for many of these exceptional athletes. The northern Patagonian ice sheet is one such place - a blank spot on the map that doesn't have much to offer apart from kilometres of ice and icy mountains. But that was precisely the decisive factor for Robert Jasper and his rope team.

THE STARTING SHOT IS FIRED

In October 2019, the four-person rope team of Jasper, Heller, Thomann and Fengler travelled to Chile. From Puerto Bertrand, they travelled by boat across Lago Plomo into the Val Soler valley, which stretches for many kilometres into the inland ice. The approach led through the wilderness and cold rainforest until they reached the base camp site after four days. What Robert and his companions didn't realise at the time was that they would be spending a lot of time at this base camp.

Untouched terrain always has a decisive disadvantage: available terrain information and existing maps are either few and far between or full of errors, which is also due to the rapidly advancing glacier melt here. In addition, there were huge icefalls and crevasses, which made progress even more difficult. These circumstances often forced the athletes to change their plans and routes. The weather also showed its rough side. Violent storms with heavy rain and snowfall meant that the athletes had to hold out at base camp time and time again, which meant lost time.

FAILED ATTEMPT FOLLOWS FAILED ATTEMPT

After a total of four weeks in the wilderness and six attempts to climb the mountain, the rope team led by LOWA PRO team athlete Robert Jasper had still not been able to climb the chosen mountain Cerro Largo (2,799 metres). The planned schedule had been completely jeopardised, meaning that food supplies were running low and had to be rationed in order to have any chance at all. And there was a chance: a window of good weather was opening up for the last possible day of the ascent. "We put all our eggs in one basket to climb Cerro Largo with light equipment, single push style. First on skis, then on increasingly steep ice and finally climbing over vertical wind-pressed snow mushrooms," the professional mountaineer reports on the not entirely safe conditions, as a mistake was always possible in these conditions. But against all odds, they had made it; they had reached the summit.

In a total of 18 hours, Jasper, Heller, Thomann and Fengler covered almost 50 kilometres and 5,000 metres in altitude from and to base camp, making them the first rope team to climb Cerro Largo non-stop.

"We were only the second group ever to reach the top of Cerro Largo. If you think about it, a summit in the world where you are the second person ever to reach it, that's quite a privilege to be allowed to stand up there." Robert Jasper | LOWA PRO Team
