"Polish climber Piotr Krzyżowski has achieved a historic feat by summiting both Mount Everest and Lhotse without the use of supplemental oxygen or the assistance of Sherpas.
Krzyżowski's accomplishment places him among an elite group of mountaineers who have conquered these two peaks in a single expedition. His ascent of Lhotse (8,516 meters) and Mount Everest (8,848 meters) was completed without descending to Everest Base Camp between summits, making his achievement even more impressive."
