Today we made an acclimatization trip to the pass (4100m) in the direction of the Advance Base Camp, from there we climbed to two points higher up the ridge: 4230m+4330m. Because we felt like it, we ran back to Base Camp. From higher up we discovered several small lakes, so we took a well deserved dive and enjoyed the beautiful weather. A good training day! Tomorrow the training ascent to Petrovsky Peak is planned.
