editor’s note

Wide World let me tell you about a photo that hangs in my house. it was taken by W. Eugene smith, and its title is “the Walk to paradise garden.” it shows his two young children, hand in hand, on a dirt path in the woods, emerging from shadows into the light of a clearing. it reminds me of myself as a young boy exploring the wilderness of my backyard in southwestern oregon. my backyard had this: my favorite black walnut tree, deer tracks, a hornet’s nest, squirrels. i would wander its seven acres, hoping to see a cougar (i never did). or go down to griffin creek, hoping to discover an arrowhead (i often did). Years later, i understood that what my backyard contained, most of all, was the infinite horizon…

Extreme Weather Very, very early Wednesday morning, August 29, 2012, while sitting in the dark (I had no power), I anxiously awaited Hurricane Isaac, making its way through our area. I tried a little reading with my flashlight to keep my mind off the rising water and picked up my new National Geographic. The rain wouldn’t stop, and the tide was rising in the bayou. I saved your article to read when the power came on. I appreciate recognizing El Niño and La Niña, melting ice, and greenhouse gases. Anyone who does not believe the Earth is warming or rejects that notion has not been in a weather disaster. CAROLYN ROUSSEAU Slidell, Louisiana Writer Peter Miller attributes the river crest forecast of 42 feet to the U.S. Army Corps of Engineers, when it…

survival guide

Facing a Glacier We were on the scent of snow leopards. But first my team and I had to cross a glacier. On the other side was a 16,000-foot Karakoram pass, and beyond that, we suspected, a snow leopard trail. Before setting out, we had asked the locals if we needed crampons or other climbing gear. They assured us we didn’t, so we took only a rope for this walk across the side of a mountain covered in ice. There were also chunks of ice in a crevasse lake below—the air temperature was hovering around 14°F. The three of us looped the rope around our stomachs to bind ourselves to each other—if one slipped, the others could stop his fall. Our local guide followed, gripping the rope in his hands. If we’d…

United States Like a spaceship gearing up to lift off, a carnival ride throws off orbs of light in this panoramic time exposure. The whirling captures the revelry of a summer’s eve at the Minnesota State Fair. PHOTO: DAVID BOWMAN Benin At a vodun celebration in Ouidah, sequined masquerades known as Egungun embody the spirits of ancestors with ties to Nigeria’s Yoruba culture. Some masked spirits bless the living; others entertain with intricate dances. PHOTO: DAN KITWOOD, GETTY IMAGES Atlantic Ocean Swelling to more than 30 feet across, a school of blue jack mackerel achieves a harmony that belies its purpose: safety from predators. The fish broke apart and re-formed off the azores as dolphins, birds, and sharks pecked away at the pack.

EDITORS’ CHOICE Trisha Ratledge Carlsbad, California Seeing her 14-year-old daughter laughing and twirling in Tokyo’s Mori Tower was the most poignant moment for Ratledge during a family trip. “It represented Emma literally dancing from one important stage in her life—middle school—to the next, high school,” says the journalist mother. READERS’ CHOICE Shelley Smart Goolwa, Australia This chunk of Antarctic ice, rising some 60 feet, greeted Smart and her mother when they toured the continent aboard a Russian icebreaker. The marine biologist and environmentalist says: “Antarctica is where you go when you want to discover what Earth used to be like.”…

Antarctic Pod There’s only one current that circles Antarctica. At the bottom of the planet, wind whips the water around and around without any land to get in the way. Because these waters are so dangerous to study, scientists depend largely on data from automated floats and summer research ships. That’s what makes explorer Jean-Louis Etienne’s new research pod important. Scheduled to be deployed in 2015, the vessel will act like a buoy and be steered by the Circumpolar Current—it’ll be towed out, then let go. Critical to Etienne’s design is a stable platform 80 feet above the water, so researchers can study how the ocean and air interact plus accurately measure salinity, temperature, and currents, nighttime and daytime, year-round. The pod might also tell scientists more about the feeding areas whales…
