A study of the Umpqua River basin in the Oregon Coast Range helps explain natural processes behind the width of valleys and provides potentially useful details for river restoration efforts designed to improve habitats for coho salmon (Oncorhynchus kisutch).
Several lakes around the world are known for their salty content. Among the most well-known are the Great Salt Lake in Utah and the Dead Sea. But these bodies of water pale in comparison to Don Juan Pond in Antarctica, known as the saltiest body of water on Earth.
What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change?
Rivers and valleys form intricate branching patterns, which have inspired some scientists to develop a theoretical understanding of river-network geometry.

MESSENGER, in orbit around Mercury since March of last year, has discovered assemblages of tectonic landforms unlike any previously found on Mercury or elsewhere in the Solar System.
Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats.

As global warming extends its balmy fingers further into the Arctic regions, defrosting permafrost could release up to 44 billion tons of nitrogen and 850 tons of carbon into the atmosphere, according to a new study from the U.S. Geological Survey.
Valles Marineris stretches over 4000 kilometers in length and is 200 kilometers wide, with a maximum depth of 10 kilometers. This makes it 10 times longer and five times deeper than the Grand Canyon, earning it the title of the largest canyon in the Solar System.
Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...
Badlands national Park is located in the southwest region of South Dakota. It holds 242,756 acres of land, with 64,144 acres comprising a protected wilderness area. The park was designated as a national monument in 1929 and established in 1939, but attained national park status in 1978. The Stronghold Unit area of the park is managed by the National Park Service and the Oglala Lakota tribe and holds many sights including those used for Ghost Dances in the 1890’s, a bomb and gunnery range...
A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
