Olympus Mons is the largest known volcanic construct in the Solar System; it is more than 600 km across and more than 27 km above datum (fig, 1, sheet 1). The volcano and the great scarp that bounds it have been the subject of much &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;scientific &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;controversy. Although i&lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;t &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;has been possible to generate an empirical model that closely resembles Olympus Mons (fig. 2, sheet 1), the &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;dynamics&lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt; of scarp formation are still unproven&lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;. The scarp area is thus a logical selection as a scientific study area. It has also &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;been designated as a &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;candidate site for a proposed &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;lander/rover/sample-return mission to Mars (fig. 1, sheet 2) not only because the site may provide &lt;/span&gt;&lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;information about the origins of the scarp and the evolution of Olympus Mons, but also&lt;/span&gt; &lt;span class="NormalTextRun SCXW159199272 BCX8"&gt;because the rocks of widely diverse ages may be studied from the samples collected from talus at the base of the scarp.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
