People enjoy themselves as they dance to Dominican music at a refugee camp for Haitians returning from the Dominican Republic on the outskirts of Anse-a-Pitres, Haiti, September 6, 2015. Dominican officials last month began implementing a controversial immigration program targeting Haitian migrants and Dominican-born people of Haitian descent. The program centers on round-ups and deportations that have triggered concerns about a slow-growing border migration crisis in the poorest country in the Americas. So far about 1,500 people have been deported at a pace of 50 to 100 per day, according to relief officials with access to records supplied by the Dominican government.

The cactus, estimated to be more than 200 years old, measures a circumference of 7 feet, 10 inches (2.4 meters) and stands 46 feet high (14 meters). The cactus was burned in the Cave Creek Complex fire and may not survive. It was once the largest Saguaro in the world, two others have been found recently that have tied it's measurements. The fire has burned more than 214,000 acres of the Sonoran desert. (Photo by Jeff Topping/Getty Images)
