Vanguard3000 Posted March 18, 2011 Share Posted March 18, 2011 Very cool. It's hard to get a sense of scale here, considering that "dune" is 1400 metres high. Quote Link to comment Share on other sites More sharing options...
arnoldo Posted March 18, 2011 Share Posted March 18, 2011 Not Arrakis, but Chasma Boreale, Mars - NASAVery cool pic, although it's not Dune it is similar to it in that they both once had water which mysteriously disappeared. The following pic IS Dune (at least the general film location for 1984 Dune. . .)http://en.wikipedia.org/wiki/File:Dunas_samalayuca.jpg Quote Link to comment Share on other sites More sharing options...
athanasios Posted March 19, 2011 Author Share Posted March 19, 2011 Space exploration has in store many surprises. Let's hope that one day we will see a similar camera view of the dunes on Titan. At least those dunes are better in scale being several kms long, ~1km wide and up to 100m tall. Of course their composition is quite different.

arnoldo Posted March 19, 2011 Share Posted March 19, 2011 Space exploration will invariably lead to many surprises but there are still plenty of mysteries on earth. For example, apparently the Sahara desert was once a fertile grasslands but due to a shift of the earth's position relative to the sun it's ecosystem changed drastically over time.How Earth’s Orbital Shift Shaped the SaharaDebate over the degree of anthropormorphic climate change is another issue which will continue to be explored. One such example of man changing a local ecosystem in fact led to the ecological novel, Dune.The sand dunes on Oregon’s coast are eons old. After the seismic activity that created the Cascade and Coast Ranges ceased around seven million years ago, glaciers formed in the mountains. The torpid movement of the glaciers crushed large rocks into smaller boulders, which washed down rivers in streams, grinding into smaller and smaller rocks until only sand and pebbles were deposited into the coastal waters. Waves carried the sand onto the beach and onshore winds then blew the sand into the dunes.In the 1930s, European beach grass was introduced to provide stable foundations for buildings and towns. The invasive beach grass has thrived and is now taking over the unique landscape. The thick and resilient grass has piled together with sand to form a 20-foot-high barrier 30 yards from the shore, blocking the flow of beach sand that is normally blown onto dunes. Because of this wall of grass and sand, a flatland of fresh water and vegetation has formed that is quickly moving east and will eventually swallow up the hills of sand. What took 100,000 years to form could be destroyed in a century.In Oregon, a Battle Over the Dunes Quote Link to comment Share on other sites More sharing options...
ErasOmnius Posted March 21, 2011 Share Posted March 21, 2011 This is not Dune, either. It is the Eye of Sauron in Morocco. Quote Link to comment Share on other sites More sharing options...
athanasios Posted March 22, 2011 Author Share Posted March 22, 2011 I think it is the remains of an ancient civilization's failed collider.What puzzles me is that it gives the impression of spires. Quote Link to comment Share on other sites More sharing options...
