cs, once again you critcising what I posted without dealing with it direectly. You wrote:<br /><br />"You've demonstrated no comprehension of what any of Carlotto's analyses are about, so I don't take your testimonials very seriously. But if you want to believe proclamations supposrted by dubious line drawings, that's OK with me."<br /><br />It is ironic that proclamations and pubious drawinms is exactly what most of us believe Carlotto is guilty of. That aside, once again, what is it that you disgarfee about my analysis. My drawings identified scree slopes, alcoves, mantled slopes, erosional terraces and benches, plains. Are you saying you can't see these features in the images? Or that you disagree with where the boundaries are? Engage the data and its interpretation, don't just wave your arms.<br /><br />Jon<br />" <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
