Peaks East of Huayna Potosí, Cordillera Real. Ours was the first expedition to the Andes from Poznan. It was both scientific and mountaineering. We made biological, geological, ethnological and meteorological studies during our seven months in the field. The following participated: Krzysztof Blauth, Tomasz Chrzan, Jacek Gutowski, Andrzej Jaskula, Andrzej Lisiecki, Leon Wawrzyniak, Zbigniew Zimny, my wife Aleksandra Grebieniow as doctor and I as leader. Our first climbing activity took place in the Cordillera Real from February 26 to March 17. Our Base Camp was on Lake Zongo at 15,785 feet, 2½ miles southeast of Huayna Potosí. We made six high camps. We made the following ascents: Khala Cruz (17,142 feet; 1 mile southwest of Lake Zonga) via north buttress on March 1 and Alhuayco (17,372 feet; east of Khala Cruz) via south ridge on March 2 by M. and A. Grebieniow, Wawrzyniak; Grincuni (16,568 feet; northeast of the former) via southeast spur by Chrzan, Lisiecki on March 1; Huiyata (16,706 feet; north of Grincuni) via south ridge by Zimny, Jaskula, Lisiecki on March 5; Charquini Norte (17,422 feet; east of Alhuayco) via north ridge by M. and A. Grebieniow, Gutowski, Wawrzyniak on March 5. All were done in rainy weather. Alhuayco was the only first ascent. (For Peruvian climbs, see that section.)
