Like every other unusual formation on Mars, this stunning feature too may have been caused by erosion. But this formation, perhaps more than most, should also provoke the question "What would a constructed monument look like after 100,000 years or more of erosion?" We must ask how many layers of dust, sediment and ice would have changed and distorted its original shape? What effect would giant tsunami's and meteoric bombardment from a planetary catastrophe have had on its structural integrity?


It has a unique five-sided, symmetrical shape. The explicit geometrical form strongly suggests intelligent design.


A remnant massif formed by geological erosion.
