The Abruzzi party had included the photographer Vittorio Sella whose magnificent photographs were used and admired by later generations of explorers, giving a fine impression of the mountain faces and ridges of K2 and its surrounding mountains. At Concordia, where the Baltoro and Godwin-Austen glaciers merge, they had travelled up the latter. From what became the traditional base camp site they explored K2's northeast ridge, which they considered hopeless, so attempted to climb up the southeast ridge - now called the Abruzzi Ridge or Spur. Two Courmayeur guides reached about but this only proved the party as a whole would not manage the climb. They then went on the western side of K2, up the Savoia Glacier to a place they called the Savoia Pass at , at the foot of the northwest ridge. Again they were thwarted so as a consolation they climbed high on Chogolisa, to about - the highest altitude ever reached and one that would not be exceeded until the 1922 British Mount Everest expedition.
