Mars Art: Dunes in Abalos Undae

This week’s Mars Art is a HiRISE view of Dunes in Abalos Undae. Pictures of sand dunes taken by HiRISE never get old for me. There is something about the undulating, regular shapes of dunes that is fascinating and beautiful and peaceful. There is a great quote about dunes in the book “Physics of Blown Sand and Desert Dunes” by R.A. Bagnold that goes on quite poetically about them, but unfortunately I don’t have it close at hand. Consider this an IOU. which Briony has posted below! Meanwhile, enjoy the picture, and read more about it here.


Update from Briony: Here’s an awesome Bagnold quote, hopefully the one that Ryan was referring to:

In places vast accumulations of sand weighing millions of tons move inexorably, in regular formation, over the surface of the country, growing, retaining their shape, even breeding, in a manner which, by its grotesque imitation of life, is vaguely disturbing to an imaginative mind.
~ Bagnold (1941)

  1. […] Prachtige foto, nietwaar? Het zijn door de wind gevormde duinen op Mars, in het gebied genaamd Abalos Undae. De foto is genomen met het High Resolution Imaging Science Experiment, oftewel HiRISE, aan boord van de Mars Reconnaissance Orbiter van de NASA. De duinen lijken net een soort dakpannen. Eerder heb ik een vergelijkbare foto gepubliceerd, van duinen die voorkomen in Olympia Undae. Die waren echter meer ‘wormachtig’. De blauwachtige kleur van de duinen in Abalos Undae komt door het basalt in de bodem. Tussendoor zie je witte delen, waar meer stof ligt. Bron: Martian Chronicles. […]

    Well if it is not rock it must be sand!
    and then there is still the rest of the grindings somewhere!
    Water? That sublimes AWAY it becomes that well known magical non substance not subject to gravity and incapable to form an atmosphere!
    Only meteorites can hold on to that stuff! Mars needs a dust cover to keep it!
