-- As part of ABC News' "50 States in 50 Days" road trip, "World News Sunday" traveled to Utah to explore the vigorous debate emerging over the federal government's plan to allow exploration and drilling for natural gas in pristine parts of the state rich in fossil fuel.
We visited Nine Mile Canyon, also known as the world's longest art gallery, thanks to some 10,000 Native American etchings carved thousands of years ago. Drilling in the canyon is in its fourth year and local conservationists are concerned that the industrial traffic will destroy the ancient petroglyphs and some of the West's most important natural habitats. But a growing part of the population there see a concrete solution to alleviating Western states' energy crunch.
