A visitor looks at gas canisters that were salvaged from trash picked from Mount Everest and made into prayer wheels during a visual art symposium in Kathmandu November 25, 2012. Fifteen Nepali artists closeted for a month with a heap of 1.5 metric tons (1.7 tons) of trash picked up from Mount Everest transformed the litter into art, creating 75 sculptures, including one of a yak and another of wind chimes, made from empty oxygen bottles, gas canisters, food cans, torn tents, ropes, crampons, boots, plates, twisted aluminium ladders and torn plastic bags dumped by climbers over decades on the slopes of the world's highest mountain. Kripa Rana Shahi, director of art group Da Mind Tree, said the sculpting - and a resulting recent exhibition in the Nepali capital of Kathmandu - was aimed at spreading awareness about keeping Mount Everest clean.
