"Stark circle of rock measuring about 60 feet [18 meters] in diameter likes in the Ténéré desert below the massif of Adrar Madet in Niger. Roughly a mile away in each of the four cardinal directions, similarly crafted arrows point away from the circle, whose origin, purpose, and age remain a puzzle."

Familiar with war’s ghosts, a Cambodian man passes a rusting antiaircraft gun left from days when all the land was a battlefield. This rusted gun is a reminder of Cambodia’s mass genocide under the Khmer Rouge rule from 1975 to 1979.

Photograph by Jodi Cobb
"In the leafy highlands of Papua New Guinea at a gathering of clans—some of them former headhunters—[photographer] Jodi Cobb was looking for beauty. 'What interested me,' she says of groups like the brightly painted Huli, 'is that men are flamboyant in this culture. They take their cues from the birds. The males are the colorful ones.'"
