The areas contain three distinct physiographic provinces that div&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;ide the quadrangle into latitud&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;in&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;al belts. The northern part of the quadrangle is dominated by cratered upland &lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;plateau, the central part &lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;by &lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;plains, the southern part by a mottled surface of rugged topography&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt; and a high density of craters subdued by erosion. In general, the oldest geologic unit occurs in the upland terrain, the youngest in the central lowlands.&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt; Large contrast in albedo were observed on Mars from Earth long before Mariner spaceflight missions. The most conspic&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;uous of these features within the quadrangle are areas of low albedo in the north and in the south that corresponds to the two main belts of high-relief terrain. The intervening region of high albedo corresponds to the central plains belt, also an area of recurrent seasonal frost. The southern polar cap extends to about 50&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt;˚&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt; S &lt;/span&gt;&lt;span class="SpellingError SCXW217649694 BCX8"&gt;lat&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt; and includes &lt;/span&gt;&lt;span class="AdvancedProofingIssue SCXW217649694 BCX8"&gt;all of&lt;/span&gt;&lt;span class="NormalTextRun SCXW217649694 BCX8"&gt; the southern belt of high relief.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
