The sun rise and the wind has faded. Today Olof, Marco and Robert will do an acclimatization trip to Berlin Camp. Mattias still has a bit of a headache and decides to rest in the camp. The rest sets off with a light backpack towards Berlin Camp.

Slowly and methodically the group is walking in a steady pace to reach higher altitude, every step requires a catch of breath and the heart rate runs wild (as so many times before on this expedition). Finally Berlin Camp is within our sight after an steep section and once again we are struck by the amazing feeling of being at this altitude. After looking around in the camp, Marco turns back down while Olof and Robert decide to go even higher. They climb a further 100 meters before turning back down.

Olof and Robert return to Nido de Condores together with Erik. He has done a succesful summit attempt during the day and is now completely exhausted but he can't stop smiling from ear to ear. Well Done! He decides to camp next to us to recover before going down to Plaza de Mulas the following day.

Mattias has spent the day carrying rocks, to improve the protection around the tents, while the others were at Berlin Camp. A Brazilian group have pitched their tents next to ours and their guide has received a recent weather forecast that indicates a bad storm is on its way. After four hours of hard work, Mattias has managed to build a 0.5 meters solid wall all the way around both tents. Now we are ready, bring it on!

Our walkie-talkies have been very useful during the expedition when we had to split the group, such as today. Today we had an unfortunate accident in which Marco's water bottle leaked and drown the radio in his backpack. Luckily, Marco spent long hours as a kid tearing apart his family's electronic devices so he could reassemble them and make them work again. Here you can see the radio disassembled to dry out the moist. The radio was later assembled and work without any problems during the rest of the trip.

We spend the rest of the day melting snow and eating cod stew (by now we are really starting to hate it!). The evening is finished off by another game of cards in the tent. Robert is accused of cheating but he claims is not on purpose. According to Robert it is the lack of oxygen that makes him doing wrong.

The bad weather is sweeping in over the mountain. We put plenty of stones over our rucksacks and bring enough food and snow into the tents in case we have to ride out the storm. The wind called Viento Blanco can reach strengths of 65 to 70 m/s. Luckily it just ended up being slightly worse than the previous night. Our Hilleberg Saivo and the Mountain Hardware Annapurna stood firm throughout the night. The guide of our Brazilian neighbours lost two North Face 25 tents the previous year in similar weather conditions.
