Merit Prize Winner: “A Well Earned Rest in the Sahara”. This photo of Moussa Macher, our Tuareg guide, was taken at the summit of Tin-Merzouga, the largest dune (or erg) in the Tadrat region of the Sahara desert in southern Algeria. Moussa rested while waiting for us to finish our 45-minute struggle to the top. It only took ten minutes of rolling, running, and jumping to get back down. The Tadrat is part of the Tassili N'Ajjer National Park World Heritage area, famous for its red sand and engravings and rock paintings of cattle, elephants, giraffes, and rhinos that lived there when the climate was milder. Photo location: Summit of Tin-Merzouga, Tadrat, Tassili N'Ajjer National Park, Algeria. (Photo and caption by Evan Cole/National Geographic Photo Contest)

Hundreds of houses painted in bright colors in what organizers claim is Mexico's largest mural, is part of a government-sponsored project is called Pachuca Paints Itself, in the Palmitas neighborhood, in Pachuca, Mexico, Thursday, July 30, 2015. German Crew is the artist collective responsible for painting the mural project. Director Enrique Gomez, who goes by MYBE, said the crew has painted 1,500 square meters with 20,000 liters of paint. Working hand-in-hand with residents, muralists have painted the facades of 200 homes bright lavender, lime green, incandescent orange – hues more commonly found in a bag of Skittles than in the drab, cement-and-cinderblock neighborhoods where many of Mexico's poor live. The project aims to bring the community together and rehabilitate the area. (Photo by Sofia Jaramillo/AP Photo)
