Elephants on Parade

In the first morning light, female elephants and their young cross the plains of Kenya’s Amboseli National Park to feed in the marshes, says Daniel Pinheiro. Mount Kilimanjaro and its famed mantle of snow looms behind.

Passing By

Passionate ski mountaineer and Peter Svoboda loves minimalist compositions in his winter-themed mountain photography. Svoboda saw this scene unfold from about a mile away on the summit of Kreuzkogel in the Austrian Alps. “The angle of [the] slope ... and [the] afternoon sun created rather attractive shapes at first sight,” he writes. “I was waiting on the top of the mountain and took some pictures with the lonely tree. But it was not enough for me.” After he’d photographed a group of skiers who were enjoying the deep powder, this lone figure “was like icing on the cake,” he writes. “The mood was there.”

The People’s Pope

At a general audience in St. Peter’s Square in Vatican City, Pope Francis rides in a popemobile without the protection of bulletproof glass. The pontiff wandered freely when he was a cardinal in Buenos Aires but cannot do so in Rome for his own safety.
