K2: The World's Second-Highest Mountain Is in Asia

The second-highest mountain on Earth is K2 (Mount Godwin-Austen), standing at 8,611 meters (28,251 feet). It is located in the Karakoram mountain range, on the border between Pakistan (Gilgit-Baltistan) and China (Xinjiang/Taxkorgan Tajik Autonomous County).

Therefore, the continent is Asia. (The highest, Everest, is also in Asia, in the Himalayas.)

K2 is notorious among mountaineers as the "Savage Mountain" for its extreme technical difficulty, unpredictable weather, and high fatality rate—far more challenging than Everest despite being 237 meters lower.
