LEH, INDIA - OCTOBER 4:  The confluence of the Indus river (L) and the Zanskar river (R) at Sangam on October 4, 2012 near to Leh in Ladakh, India. Ladakh, nestled between the Kunlun mountain range in the north and the main Great Himalayas to the south, was once an ancient Buddhist Kingdom and for over half a century now, a strategic military outpost for India. Ladakh, sharing borders with both China and Pakistan, has seen an increase in tourism over the last few years, an alternative to Nepali Himalayan treks. (Photo by Daniel Berehulak/Getty Images)
