Photograph by Randy Olson
A Sudanese man illuminates hieroglyphs in an ancient tomb in Al Kurru. Sudan is strewn with the ruins of Nubian kings, who once ruled all of Egypt. Today, Sudan's government struggles to control its own country, paralyzed by decades of civil, ethnic, and religious conflict.

Photograph by Bill Curtsinger
A crack in the ice shelf, called a lead, gives a diver access to (and escape from) the frigid waters of Antarctica's McMurdo Sound. Those who brave the water temperatures of 28 degrees Fahrenheit (minus 2.2 degrees Celsius) here are rewarded with unsurpassed visibility and unique sea life that has developed in isolation for some 40 million years.

Photograph by Carsten Peter
Zebu cattle driven by Afar herdsmen raise clouds of dust in the baked Danakil Desert near Semerea, Ethiopia. The Danakil is among the most forbidding places on Earth, a land of dry sands, active volcanoes, burning salt flats, temperatures that often top 120 degrees Fahrenheit (49 degrees Celsius), choking winds, and suffocating days of no wind at all.

Light shines between the ice blocks of an igloo in Moriusaq, Greenland. Igloos are usually dome-shaped and are made of large slabs cut from compacted snow. A skilled native Greenlander can build one in just a couple of hours.
