What if Duck Bay disappears?

[brellis]

I was just looking at the Opportunity Route Map, and I wondered what scale of calamity would it take to change the nature of the edge of Victoria Crater?<br /> <br />MRO pics have shown recent gully activity has occured elsewhere on Mars in the past few years. Theories include collapses underground.<br /><br />Could an underground event cause one of the capes to collapse?<br /><br />Have they established that the area around Victoria has been inactive for a substantial period? By inactive I do not mean to imply water, just things like rockslides.<br /> <br />Is that area of Mars dormant enough to assure the rover operators that Victoria and all of its recently-named features will remain in place for the time being? <div class="Discussion_UserSignature"> <p><font size="2" color="#ff0000"><em><strong>I'm a recovering optimist - things could be better.</strong></em></font> </p> </div>
