Concordia – Sublime Alpine Amphitheater
The Baltoro Glacier, one of the longest glaciers on the planet outside the earth's arctic and polar realms, descends roughly 30 miles from its source high in the Karakoram range of the Himalaya in Northern Pakistan to its terminal moraine at the head of the Braldu River. A river of ice that has inexorably snaked toward lower ground and has carved a two and one-half-mile-wide valley over millennia, the Baltoro glacier is a passageway to vistas of sheer granite towers and pyramids of ice-veneered rock. A journey into the Baltoro brings first-hand views of fantastic peaks, such as the Trango Towers, Broad Peak, the Gasherbrum group of peaks, and K2, the planet's second highest mountain. K2 is, according to some of history's most accomplished mountaineers, the king of all the earth's mountains, primarily due to its incredibly severe weather.
