A recent Mars Express image reminded of the form of peaks sometimes seen underwater. Look at the sonogram below of the Adare seamounts:<br /><br />http://images.google.com/images?q=tbn:0L82tcmf2scJ:http://www.es.usyd.edu.au/geology<br /><br />See also the first image on this page:<br /><br />Seamount Studies<br />http://www.awi-bremerhaven.de/Modelling/BRIOS/seamount.html<br /><br /> These images of underwater peaks show separate, conical peaks closely spaced.<br /><br /> They may be analogous to this image of Eos Chasma:<br /><br />Eos Chasma, part of Valles Marineris.<br />http://esamultimedia.esa.int/images/marsexpress/0533_co_Eos_ortho.jpg<br /><br /><br /> Bob Clark<br /> <div class="Discussion_UserSignature"> </div>
