Inverted Topography - On Mars

On Mars

Inverted relief in the form of sinuous and meandering ridges, which are indicative of ancient, inverted fluvial channels, is argued to be evidence of water channels on the Martian surface in the past. An example is Miyamoto Crater, which was proposed in 2010 as a potential location to be searched for evidence of life on Mars.

Other examples are shown in the photographs below.

Famous quotes containing the word mars:

    What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.
    Henry David Thoreau (1817–1862)

    Venus me yaf my lust, my likerousnesse,
    And Mars yaf me my sturdy hardinesse.
    Geoffrey Chaucer (1340?–1400)
