A solar phenomenon known as a sundog arcs over the tundra in Churchill, Manitoba, Canada. Sundogs are fairly common occurrences in the Arctic and Antarctic. They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.

Bullfight, Arequipa, Peru, 1982
Photograph by William Albert Allard
A slow exposure blurs the charge of a bull at a bullfight in Arequipa, Peru. Peru is the second stop on the calendar for many of the world's top bullfighters. They begin in Spain in March, move to Lima for a month in October, then head to Mexico to close the year.

Spawning Salmon, Alaska, 1999
Photograph by Karen Kasmauski
Salmon en route to spawning grounds struggle up an intertidal stream on a stretch of Alaskan coastline once fouled by millions of gallons of crude oil from the infamous Exxon Valdez. Today, a visitor would be hard pressed to find evidence of the spill. But studies show lingering effects to regional wildlife.

Fourth of July Fireworks, Bowlus, Minnesota, 2000
Photograph by Richard Olsenius
Fireworks light up the sky over a grain elevator in Bowlus, Minnesota. The volunteer fire department sets off the display every year on the Fourth of July, during Bowlus Fun Days. The daylong celebration is a "big thing" in Bowlus, says Charlie Sobieck, who owns the grain elevator. "We have bingo, a snow-cone stand, cotton candy, polka bands, and a parade with floats. It's a good gathering for people to see people they haven't seen in years."

Photograph by Tim Laman
A giant squirrel surveys the surrounding rain forest from a tree limb in Borneo’s Gunung Palung National Park. Borneo, the world’s third largest island, boasts some of the last areas of pristine rain forest in the world. However, deforestation from illegal logging within the park threatens the survival of this unique ecosystem.

Photograph by Maria Stenzel
Ariaal warriors rest on an outcrop amid the deserts of northern Kenya's Marsabit District. The 10,000 or so Ariaal who inhabit Marsabit have managed to maintain their nomadic way of life in spite of shrinking communal pastures, increasing ethnic tensions, and government pressure to trade their cattle culture for a more mainstream existence.

Headlights, Imperial Sand Dunes, California, 2005
Photograph by Gerd Ludwig
Headlights stream up and down the fluid banks of Imperial Sand Dunes, southeast of California's Salton Sea, in this time exposure. An off-roaders' paradise, the dunes were blown from the dry bed of Lake Cahuilla, the sea's ancient ancestor. More than a million fans hit the dunes each year, pumping $54 million into local coffers. The cost? Brawls, fatal crashes, and run-ins with endangered species.

A spacesuit is put through its paces at the Johnson Space Center's Lunar Yard in Houston, Texas. The 2-acre (0.8-hectare) mock moon surface, made of sand and crushed granite, allows engineers to test systems and concepts as they prepare for NASA's return to the moon.

Sunken Treasure Hunters, Atlantic Ocean, 1999
Photograph by Priit Vesilind
A small boat tows a Russian submersible during a 1995 expedition to find sunken gold. The mission sought to raise more than 2 tons (1.8 metric tons) of bullion from a Japanese submarine torpedoed by American forces off Africa's Atlantic coast during World War II. Disappointed treasure hunters recovered only some tin, brass, and an old shoe.

Wallace's Flying Frog, Borneo, 2000
Photograph by Tim Laman
Silhouetted against the night sky, a Wallace's flying frog (Rhacophorus nigropalmatus) glides through the air in Borneo. These frogs, the largest of Borneo's flying frogs, gather on branches above murky pools to breed and lay eggs. The pools then make ideal habitat for tadpoles, which drop into the water when they hatch.
