  <dc:description>&lt;p&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;The region centered at Elysium Mons &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;contains that second largest volcanic complex on Mars, surpassed in size by only the &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;Tharsis&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt; complex. The Elysium region also has been a center of tectonic, fluvial&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;, and mass-wasting&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt; activity. After degradation of &lt;/span&gt;&lt;span class="ContextualSpellingAndGrammarError SCXW26390835 BCX8"&gt;ancient cratered&lt;/span&gt; &lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;terrain within the northern lowlands, volcanic rocks erupted &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;from Elysium Mons, &lt;/span&gt;&lt;span class="SpellingError SCXW26390835 BCX8"&gt;Hecta&lt;/span&gt;&lt;span class="SpellingError SCXW26390835 BCX8"&gt;s&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt; Tholus, and &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;Albor&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt; Tholus in Elysium Planitia. The volcanic activity&lt;/span&gt; &lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;was associated with episodes of channel formation, faulting, &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;and apparent volcano/ground-ice modifications of some areas&lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;. On &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;this map sheet we portray, describe, and &lt;/span&gt;&lt;span class="NormalTextRun SCXW26390835 BCX8"&gt;interpret the rich geologic history of the region.&lt;/span&gt;&lt;/p&gt;</dc:description>
