ESA Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA’s Mars Express on 4 January. The ‘twin’ craters are in the Thaumasia Planum region, a large plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System. The northernmost (right) large crater in this scene was officially given the name Arima in early 2012, but the southernmost (left)...
If you've ever stood on a hill during a rainstorm, you've probably witnessed landscape evolution, at least on a small scale: rivulets of water streaming down a slope, cutting deeper trenches in the earth when the rain turns heavier. It's a simple phenomenon that scientists have long believed applies to large-scale landforms as well — that is, rivers cut faster into mountains that receive heavier precipitation. It's thought that if rainfall patterns influence how rivers cut into rock,...
redOrbit Staff & Wire Reports - Your Universe Online Ever since a 20-foot sinkhole opened up beneath a Florida home on February 28, swallowing up an entire bedroom and resulting in the death of one of the residents, these natural phenomena have become fixtures in both newspaper headlines and the public consciousness. But what exactly are sinkholes? “Geologically, a sinkhole is a depression in the ground that has no natural external surface drainage. Basically this means that when...
As the Colorado River winds through the Colorado Plateau's soft sedimentary strata, it picks up a tremendous amount of sediment. This sediment – which once left the river's waters so muddy that Spanish explorers christened it El Rio Colorado "the reddish river" – is a vital component to the unique ecosystems of the river. However, with the construction of the Hoover and Glen Canyon dams, which trap the sediment, the once-turbid waters have become a dazzling blue-green, signaling major...
Alan McStravick for redOrbit.com – Your Universe Online The lush tropical island of Puerto Rico is completely covered with plants and fauna. The exception to this rule resides on the large, majestic, flat-topped promontory known as El Yunque. El Yunque, Spanish for “the anvil,” rises high into the sky above the rivers and streams that run below, and has been a Puerto Rican icon since pre-Columbian times. Researchers from the National Science Foundation’s (NSF) Luquillo Critical...

(TSX-V: RDU) is pleased to announce that it has signed a binding agreement (the "Agreement") with a private exploration company (the "Optionor") to option a 10,800 hectare property which hosts a low-sulphidation, epithermal silver-gold vein system located approximately 80 km ENE of the city of Guanajuato in Mexico. Radius has named the project "Santa Brígida" after the Santa Brígida vein, one of the historically mined...
Lee Rannals for redOrbit.com – Your Universe Online More evidence is pointing to the nightmare scenario that global warming is taking a toll on our planet. Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil. If the thawing of Siberia's permafrost occurs, it could see that over 1,000 gigatons of the greenhouse gases carbon dioxide and methane are...
Lawrence LeBlond for redOrbit.com - Your Universe Online Editor's note (Feb 16): This story earlier reported that thermokarst failures were occurring do to permafrost melt. However, permafrost doesn't melt, it thaws. The changes have been made to this story to reflect that. Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate. This release is being caused by...

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 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....
