The story goes that in recent years, Jeff Clapp has made eco-art that helps preserve the sanctity of Mt. Everest’s natural beauty, and extends the value of a particular bit of Himalayan adventurers’ waste: oxygen canisters. Clapp has collected a number of the tanks that once littered Everest, and has crafted them into bells, bowls and ornaments.
