The perpetual debate continues throughout Wyoming: natural gas drilling and mineral extraction versus recreation and conservation. The Pinedale anticline south of Jackson Hole in Wyoming has been heavily drilled for gas in recent years, sometimes marring the once crystalline Teton views. The Berkeley Pit in Butte, Montana, is a stark reminder of the price to be paid, a mile-long gash in the earth where a copper-rich mountain once stood.

Numerous lodgings in the area have initiated procedures to be greener, from recycling to water conservation programs. At Teton Village in Wyoming, Hotel Terra (tel. 800/631-6281; www.hotelterrajacksonhole.com) is the first LEED-certified hotel in the state. The "localvore" movement is especially strong in Montana in the Whitefish, Missoula, and Bozeman.

In Yellowstone and Grand Teton national parks, heavy summer auto traffic and the annual impact of millions of human beings have raised questions about the sustainability of these national parks. But a visit to Yellowstone and Grand Teton national parks can be a relatively green vacation. In Yellowstone, concessionaire Xanterra Parks & Resorts (tel. 866/439-7375 or 307/344-7311; www.travelyellowstone.com), has implemented numerous environmental initiatives, including a recycling program, sourcing seafood from sustainable fisheries, and encouraging guests to reuse towels and conserve heat. Campgrounds have recycling bins near the entrance. In Grand Teton, the Grand Teton Lodge Company (tel. 800/628-9988 or 307/543-2811; www.gtlc.com) has also implemented very successful sustainability programs to lessen the human impact on the park. The company purchased wind credits to offset its energy use and diverted 50% of its waste into reusing and recycling everything from aluminum cans to horse manure to food waste. But perhaps the best way to look at sustainability is by connecting with the parks' wild soul by hiking the trails and camping in campgrounds. One of the best ways to lessen one's impact is to go off the grid on an overnight backpacking trip. Leave No Trace (www.lnt.org) is the backpacker's ethic to leave any campsite in the same condition -- or better -- than when one found it. Backpacking is a refreshing counterpoint to modern life that will give perspective on the issues of sustainability and personal energy dependence.
