Scrabble Enhansing Word : Dreikanter

I'm reading this fascinating book by Carl Sagan called The Demon-Haunted World: Science as a Candle in the Dark . Among other brain stunning words, I came across  

Dreikanter is a german word meaning three sides. It is used to call naturally occuring pyramids found in Antartica but also on Mars. These pyramids, as Carl Sagan explains so expertly, are "generated by wind erosion - the splatter of fine particles picked up by strong winds blowing in the same direction and, over the years, sculpting what once were irregular hummocks into nicely symmetrical pyramids."

This picture of Mars' surface led many people to believe in the presence of life on Mars. Scientists now explain these rock formations through wind erosion. [Picture Credits Erol Torun]
Take care!

  1. j'ai vue un reportage l'année passée sur ce phénomène mais il faisait des liens entre ca, les maya, les extraterrestres et la fin du monde c'était un peu n'importe quoi. Je suis contente de voir qu'ils ont trouvé une explication plus rationnelle ...merci :)
