|Carbon Dioxide may have carved colossal canyons |
Against the common belief, geologist and report author Nick Hoffman announced his theory that carbon dioxide carved the many canyons on Mars and not water. The more commonly accepted view says that liquid water once erupted from deep underground aquifers to carve the many canyons on Mars. Hoffman's theory is in dispute, since coastlines and pooling evidence can be found downstream from such canyons as the great Vallis Marinaris, shown below. Red Colony.com and other terraforming resources still hold to the theory that water, has, and still can be found on Mars.
