NASA has revealed a new analysis of airborne radar data collected in 2012 which shows that the instruments detected the presence of a massive sinkhole that later collapsed and forced people to be evacuated in the Bayou Corne, Louisiana region later on that year.
WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and
The shared geological features found in U-shaped bedrock canyons both in south-central Idaho and on the surface of Mars are likely the result of massive floods, according to research appearing in the journal Proceedings of the National Academy of Sciences.
West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East Antarctica.
Millions of people across the world live or depend on deltas for their livelihoods.
USGS hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed.
The high cliffs of Eastern Siberia – which mainly consist of permafrost – continue to erode at an ever quickening pace.
Last month's torrential rains and flooding in Colorado made headlines, but there's another, far more common and growing weather-related threat western states are facing in the wake of longer and worsening fire seasons: flash floods and debris flows. These runaway freight trains made of rock, mud, and water can barrel down mountain channels with little or no warning and take out roads, homes, and anything else in their path.
Ripped apart by tectonic forces, Hebes Chasma and its neighboring network of canyons bear the scars of the Red Planet’s early history.
After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on Hawaiian islands.
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....
