  <dc:description>&lt;p&gt;Officer&lt;span&gt;'s&amp;nbsp;&lt;/span&gt;Cave&lt;span&gt;&amp;nbsp;is the uppermost of four rapidly eroding&amp;nbsp;&lt;/span&gt;cave&lt;span&gt;&amp;nbsp;levels constituting&amp;nbsp;&lt;/span&gt;a&lt;span&gt;&amp;nbsp;cavern complex about 700 feet long developed chiefly&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;clay and silt. Its outer room is 35 feet by 43.5 feet by 100 feet and slopes about 45° east into the western end of&amp;nbsp;&lt;/span&gt;a&lt;span&gt;&amp;nbsp;narrow linear hill called&amp;nbsp;&lt;/span&gt;Officer&lt;span&gt;'s&amp;nbsp;&lt;/span&gt;Cave&lt;span&gt;&amp;nbsp;Ridge. Dry valleys, blind valleys, hanging valleys, sinkholes, pipes, caves, and natural bridges are abundant. These, together with subterranean drainage, give the area&amp;nbsp;&lt;/span&gt;a&lt;span&gt;&amp;nbsp;karstlike development. For such terrains the term "&lt;/span&gt;pseudokarst&lt;span&gt;" is applied. These pseudokarsts are the product of piping and are fairly widespread over the world's drylands.&lt;/span&gt;&lt;/p&gt;</dc:description>
