Earth Art: Islandic Tiger - The Eyjafjorour Fjord, Iceland - This stretch of Iceland's northern coast resembles a tiger's head complete with stripes of orange, black, and white. The tiger's mouth is the great Eyjafjorour, a deep fjord that juts into the mainland between steep mountains. The name means "island fjord," derived from the tiny, tear-shaped Hrisey Island near its mouth. The ice-free port city of Akureyri lies near the fjord's narrow tip, and is Iceland's second largest population center after the capital, Reykjavik.

arth Art: Bogda Mountains The Turpan Depression, nestled at the foot of China's Bogda Mountains, is a strange mix of salt lakes and sand dunes, and is one of the few places in the world that lies below sea level. -- Image taken by Landsat 7 on Sep. 1, 1999 -- Earth Art Photo: USGS/NASA

Earth Art: Cabo San Antonio Several hundred kilometers southeast of Buenos Aires, Cabo San Antonio juts out into the Atlantic Ocean along the Argentinean Coast. - Image taken by Landsat 7 on Nov. 21, 2002 -- Earth Art Photo: USGS/NASA

Earth Art: Campeche Named after the ancient Mayan Province of Kimpech, the state of Campeche comprises much of the western half of Mexico's Yucatan Peninsula. Rivers in southern Campeche drain into the immense Terminos Lagoon, the entrance to which is protected by a long barrier island, Isla Del Carmen. -- Image taken by ASTER on May. 2, 2002 -- Earth Art Photo: USGS/NASA

Earth Art: Colima Volcano Snow-capped Colima Volcano, the most active volcano in Mexico, rises abruptly from the surrounding landscape in the state of Jalisco. Colima is actually a melding of two volcanoes, the older Nevado de Colima to the north and the younger, historically more active Volcan de Colima to the south. Legend has it that gods sit atop the volcano on thrones of fire and ice. Image taken by ASTER on Feb. 6, 2003 - Earth Art Photo: USGS/NASA

Earth Art: Delta Region, Netherlands - Along the southern coast of the Netherlands, sediment-laden rivers have created a massive delta of islands and waterways in the gaps between coastal dunes. After unusually severe spring tides devastated this region in 1953, the Dutch built an elaborate system of dikes, canals, dams, bridges, and locks to hold back the North sea. - Image taken by ASTER on Sep. 24, 2002 - Earth Art Photo: USGS/NASA

Earth Art: Demini River, Brazil A marsh-like area borders the Demini River in northwestern Brazil. The Demini eventually joins the Amazon River. Image taken on March 15, 2000 -- Earth Art Photo: USGS/NASA

Earth Art: Desolation Canyon - Utah's Green River flows south across the Tavaputs Plateau (top) before entering Desolation Canyon (center). The Canyon slices through the Roan and book Cliffs - two long, staircase-like escarpments. Nearly as deep as the Grand Canyon, Desolation Canyon is one of the largest unprotected wilderness areas in the American West. - Image taken by Landsat 7 on Dec. 31, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Ganges River Delta The Ganges River forms an extensive delta where it empties into the Bay of Bengal. The delta is largely covered with a swamp forest known as the Sunderbans, which is home to the Royal Bengal Tiger. -Image taken on Feb. 28, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Negro River, Brazil - Fed by multiple waterways, Brazil's Negro River is the Amazon River's largest tributary. The mosaic of partially-submerged islands visible in the channel disappears when rainy season downpours raise the water level. - Image taken by Landsat 7 on Aug. 31, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Kamchatka Peninsula - The eastern side of Russia's Kamchatka Peninsula juts into the Pacific Ocean west of Alaska. In this winter image, a volcanic terrain is hidden under snow-covered peaks and valley glaciers feed blue ice into coastal waters. - Image taken by ASTER on Feb. 17, 2002 - Earth Art Photo: USGS/NASA

Earth Art: Lake Disappointment - Surrounded by sand dunes, Lake Disappointment is an ephemeral salt lake in one of the most remote areas of Western Australia. An early explorer supposedly named the lake in 1897 after following a number of creeks that he thought would lead to a large lake; they did, but the lake's extremely salty water was not drinkable. - Image taken by ASTER on Dec. 31, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Malaspina Glacier - The tongue of the Malaspina Glacier, the largest glacier in Alaska, fills most of this image. The Malaspina lies west of Yakutat Bay and covers 1,500 sq. MI (3,880 sq. km). - Image taken on Aug. 31, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Namib Desert, Namibia - Namib-Naukluft National Park is an ecological preserve in Namibia's vast Namib Desert. Coastal winds create the tallest sand dunes in the world here, with some dunes reaching 980 feet (300 meters) in height. - Image taken on Aug. 12, 2000 - Earth Art Photo: USGS/NASA

Earth Art: Niger River, Massina Mali - Coursing through parched, landlocked Mali in Western Africa, the Niger River skirts the edge of the dune-striped Sahara before turning sharply south to join the Bani River. At the confluence of the two rivers is an inland delta complete with narrow, twisting waterways, lagoons, and tiny islands.-Image taken by ASTER on Feb. 8, 2003 - Earth Art Photo: USGS/NASA

Earth Art: Syrian Desert - Between the fertile Euphrates River valley and the cultivated lands of the eastern Mediterranean coast, the Syrian Desert covers parts of modern Syria, Jordan, Saudi Arabia, and Iraq. - Image taken by Landsat 7 on Nov. 6, 2000 Earth Art Photo: USGS/NASA

Earth Art: Vatnajökull Glacier Ice Cap - Valley glaciers appear as fingers of blue ice reaching out from the Vatnajökull Glacier in Iceland's Skaftafell National Park. The park lies on the southern edge of Vatnajökull, Europe's largest icecap. - Image taken by Landsat 7 on Aug. 4, 1999 - Earth Art Photo: USGS/NASA

Earth Art: Volcanoes, Chile – Argentine - Steep-sided volcanic cones along the Chilean-Argentinean border add texture to this "study in blue." Of approximately 1800 volcanoes scattered across this region, 28 are active. - Image taken by ASTER on Feb. 1, 2002 - Earth Art Photo: USGS/NASA

Earth Art: Volga River Delta - Where the Volga River flows into the Caspian Sea, it creates an extensive delta. The Volga Delta is comprised of more than 500 channels, and sustains the most productive fishing grounds in Eurasia. - Image taken by Landsat 7 on Aug. 29, 2000 - Earth Art Photo: USGS/NASA

Earth Art: West Fjords, Island - The West Fjords are a series of peninsulas in northwestern Iceland. They represent less than one-eighth the country's land area, but their jagged perimeter accounts for more than half of Iceland's total coastline. - Image taken on June 6, 2000 - Earth Art Photo: USGS/NASA

Great Salt Desert, Iran Like poster paints run wild, this image reveals an eclectic montage of landscapes in Iran's largest desert, the Dasht-e Kavir, or Great Salt Desert. The word kavir is Persian for salt marsh. The almost-uninhabited region covers an area of more than 77,000 square kilometers [29,730 square miles] and is a mix of dry streambeds, desert plateaus, mudflats and salt marshes. Extreme heat, dramatic daily temperature swings, and violent storms are the norm in this inhospitable place. Image taken by Landsat 7 on Feb. 10, 2003 Images: USGS/NASA

Belcher Islands, Canada Like sweeping brushstrokes of pink and green, the Belcher Islands meander across the deep blue of Canada's Hudson Bay. The islands' only inhabitants live in the small town of Sanikiluaq, near the upper end of the middle island. Despite the green hues in this image, these rocky islands are too cold to sustain more than a smattering of low-growing vegetation. Image taken by Landsat 5 on Sep. 21, 2001 Images: USGS/NASA

Erg Iguidi, Algeria What look like pale yellow paint streaks slashing through a mosaic of mottled colors are ridges of wind-blown sand that make up Erg Iguidi, an area of ever-shifting sand dunes extending from Algeria into Mauritania in northwestern Africa. Erg Iguidi is one of several Saharan ergs, or sand seas, where individual dunes often surpass 500 meters — nearly one-third of a mile — in both width and height.

Caicos Islands in the northern part of the Caribbean - a popular place among tourists, known for its beautiful beaches, clear waters, scuba diving and luxury hotels. The islands are located along the northern perimeter of the submerged platform sludge formed from sand, seagrass and coral reef area of 6,140 sq.km. On this color-coded image platform presented turquoise, and vegetation - red. (USGS and NASA)

Like a distant galaxy in the clouds of interstellar dust, chunks of drifting ice floating on a graceful spirals of ice-water Gulf of Fox near Baffin Island in the Canadian Arctic. Sea ice is often formed as a dirty film of ice crystals on the surface of the ocean. As the temperature ice condenses and coalesces into large chunks of solid ice. (USGS and NASA)

During the last glacial period Akimiski Island in Canada's James Bay was under the vast glaciers that pressed an incredible force. As climate change and melting ice Akimiski began to move back. Slowly but surely increase recorded along the natural boundary, where the shoreline as if relief is engraved rings - the result of raising the land and wave action at the previous level of the sea. (USGS and NASA)

Mississippi River Small, blocky shapes of towns, fields, and pastures surround the graceful swirls and whorls of the Mississippi River. Countless oxbow lakes and cutoffs accompany the meandering river south of Memphis, Tennessee, on the border between Arkansas and Mississippi. The "mighty Mississippi" is the largest river system in North America. Image taken by Landsat 7 on May 28, 2003 Images: USGS/NASA

Gotland, Sweden In the style of Van Gogh's painting Starry Night , massive congregations of greenish phytoplankton swirl in the dark water around Gotland, a Swedish island in the Baltic Sea. Phytoplankton are microscopic marine plants that form the first link in nearly all ocean food chains. Population explosions, or blooms, of phytoplankton, like the one shown here, occur when deep currents bring nutrients up to sunlit surface waters, fueling the growth and reproduction of these tiny plants.

Eyjafjorour Fjord, Iceland This stretch of Iceland's northern coast resembles a tiger's head complete with stripes of orange, black and white. The tiger's mouth is the great Eyjafjorour, a deep fjord that juts into the mainland between steep mountains. The name means "island fjord," derived from the tiny, tear-shaped Hrisey Island near its mouth. The ice-free port city of Akureyri lies near the fjord's narrow tip, and is Iceland's second largest population center after the capital, Reykjavik.

Byrd Glacier, Antarctica Truly a river of ice, Antarctica's relatively fast-moving Byrd Glacier courses through the Trans-Antarctic Mountains at a rate of 0.8 kilometers [0.5 miles] per year. More than 180 kilometers [112 miles] long, the glacier flows down from the polar plateau (left) to the Ross Ice Shelf (right). Long, sweeping flow lines are crossed in places by much shorter lines, which are deep cracks in the ice called crevasses. The conspicuous red patches indicate areas of exposed rock.

Yukon Delta, Alaska After beginning in northern British Columbia and flowing through Yukon in Canada, the Yukon River crosses Alaska before emptying into the Bering Sea. Countless lakes, sloughs, and ponds are scattered throughout this scene of the Yukon Delta. The river's sinuous, branching waterways seem like blood vessels branching out to enclose an organ. It is one of the largest river deltas in the world, and currently protected as part of the Yukon Delta National Wildlife Refuge. Image taken by Landsat 7 on Sep. 22, 2002 Images: USGS/NASA

Rocky Mountains, Canada What appears to be a stroke of thick red paint is actually a remarkable interplay of light and cloud in the Canadian Rockies. Angling through them is part of the Rocky Mountain Trench, a valley that extends from Montana to just south of the Yukon. Low clouds filled a part of the trench near the border between the Canadian provinces of Alberta and British Columbia. The light-reflecting nature of the clouds coupled with low sun elevation resulted in this startling effect. Image taken by Landsat 5 on Feb. 1, 2007 i mages: USGS/NASA

Great Barrier Reef, Australia What might be mistaken for dinosaur bones being unearthed at a paleontological dig are some of the individual reefs that make up the Great Barrier Reef, the world's largest tropical coral-reef system. The reef stretches more than 2,000 kilometers [1,240 miles] along the coast of Queensland, Australia. It supports astoundingly complex and diverse communities of marine life and is the largest structure on the planet built by living organisms.

Empty Quarter, Saudi Arabia–Yemen Border White pinpricks of cloud cast ebony shadows on the Rub' al Khali, or Empty Quarter, near the border between Saudi Arabia and Yemen. The lines of wind-sculpted sand are characteristic of immense sand deserts, or sand seas, and the Rub' al Khali is the largest desert of this type in the world. A highland ridge is just high enough to disturb the flow of the lines. In the center of that interruption lies the Saudi Arabian town of Sharurah.

Liverpool Bay, Canada Skeletal extensions of land reach like bony fingers across a section of Liverpool Bay along the northern edge of Canada's Northwest Territories. Only small villages are thinly scattered in this remote and inhospitable region of Arctic tundra bordering the Beaufort Sea. The relatively flat landscape is dotted with shallow lakes during the extremely brief summer season. Image taken by Landsat 5 on Jul. 26, 2007 i mages: USGS/NASA

Aland Islands, Baltic Sea Ethereal swirls of grease ice appear turquoise against the midnight blue of the northern Baltic Sea near the Aland Islands (red) between Finland and Sweden. An early stage of sea-ice formation, grease ice consists of a viscous mix of tiny ice crystals and resembles an oil slick on the ocean's surface. Wind and currents constantly shape and reshape grease ice into surreal, ghostly patterns. Image taken by Landsat 7 on Apr. 19, 2003 i mages: USGS/NASA

Okavango River, Botswana Like a watercolor in which a brushstroke of dark green has bled into a damp spot on the paper, southern Africa's Okavango River spreads across the pale, parched landscape of northern Botswana to become the lush Okavango Delta. The delta forms where the river empties into a basin in the Kalahari Desert, creating a maze of lagoons, channels and islands where vegetation flourishes, even in the dry season, and wildlife abounds.

Greenland Coast Along the southeastern coast of Greenland, an intricate network of fjords funnels glacial ice to the Atlantic Ocean. During the summer melting season, newly calved icebergs join slabs of sea ice and older, weathered bergs in an offshore slurry that the southward-flowing East Greenland Current sometimes swirls into stunning shapes. Exposed rock of mountain peaks, tinted red in this image, hints at a hidden landscape. Image taken by Landsat 7 on May 21, 2001 iM ages: USGS/NASA

Erg Chech, Algeria Seen through the "eyes" of a satellite sensor, ribbons of Saharan sand dunes seem to glow in sunset colors. These patterned stripes are part of Erg Chech, a desolate sand sea in southwestern Algeria, where the prevailing winds create an endlessly shifting collage of large, linear sand dunes. The term erg is derived from an Arabic word for a field of sand dunes. Image taken by Landsat 7 on Apr. 13, 2003 Images: USGS/NASA

Mount Elgon, Uganda-Kenya Border Clouds encircle the lofty rim of Africa's Mount Elgon, a huge, long-extinct volcano on the border between Uganda and Kenya. The solitary volcano has one of the world's largest intact calderas, a cauldron-like central depression. The caldera is about 6.5 kilometers [4 miles] across. It formed following an eruption, when the emptied magma chamber collapsed under the weight of volcanic rock above it. Image taken by Landsat 5 on Aug. 9, 1984 i mages: USGS/NASA

Dhofar Region, Oman Much of Oman is desert, but the Arabian Sea coast in the Dhofar region represents a startling difference in climate. This coastal region catches the monsoon rains, or khareef , during the summer months. Drenching rains fall primarily on the mountainous ridge that separates the lush, fertile areas along the coast from the arid interior, recharging streams, waterfalls and springs that provide plentiful water supplies in the fertile lowlands for the remainder of the year. Image taken by Landsat 5 on Apr. 2, 2005 i mages: USGS/NASA

Chaunskaya Bay, Russia Vivid colors and bizarre shapes come together in an image that could be an imaginative illustration for a fantasy story. This labyrinth of exotic features is present along the edge of Russia's Chaunskaya Bay (vivid blue half circle) in northeastern Siberia. Two major rivers, the Chaun and Palyavaam, flow into the bay, which in turn opens into the Arctic Ocean. Ribbon lakes and bogs are present throughout the area, created by depressions left by receding glaciers. Image taken by Landsat 5 on June 15, 2005 i mages: USGS/NASA

Meighen Island, Canada A veil of blowing snow nearly obscures Meighen Island (left) off the northern coast of Canada. Across the Sverdrup Channel lies the much larger Axel Heiberg Island, where glaciers (blue) huddle among mountain peaks (yellow) and flow into deep fjords. No evidence of human occupation has ever been found on Meighen Island. Image taken by Landsat 7 on June 14, 2000 i mages: USGS/NASA

Waziristan Hills, Pakistan Deep purple and green hues enhance the Waziristan Hills, a mountainous region of northwest Pakistan near the Afghanistan border. A formidable landscape, the Waziristan Hills are a hodgepodge of steep, rugged hills split by narrow passes and deep gorges. Rivers coursing down from the mountains provide water for agriculture in a region of scanty rainfall. Image taken by Landsat 7 on Apr. 28, 2001 i mages: USGS/NASA

Dardzha Peninsula, Turkmenistan Looking like a monstrous ogre with something gooey in its mouth, the Dardzha Peninsula in western Turkmenistan lies among the shallow coastal terraces of the Caspian Sea. Strong winds create huge sand dunes near the water, some of which are partly submerged. Farther inland, the dunes transition to low sand plains.
