  <dc:description>&lt;p&gt;&lt;span&gt;Geologic interest in&amp;nbsp;&lt;/span&gt;Thorne&lt;span&gt;&amp;nbsp;&lt;/span&gt;Cave&lt;span&gt;&amp;nbsp;stems from its link with valley alluvium along Cliff Creek, which accumulated to a height of 48 ft., continued to build up another 13 ft. while men lived here, and then reached 30 ft. higher-sealing in the signs of man. Mineralogic study shows that ground water then circulated through the&amp;nbsp;&lt;/span&gt;cave&lt;span&gt;&amp;nbsp;deposits for a considerable time. The alluvium is correlated with the lower part of the Tsegi Formation of the Navajo country. Cutting of a terrace at mid-depth in the valley alluvium reopened&amp;nbsp;&lt;/span&gt;Thorne&lt;span&gt;&amp;nbsp;&lt;/span&gt;Cave&lt;span&gt;, probably before the Christian era, and desert varnish then began to form on the&amp;nbsp;&lt;/span&gt;cave&lt;span&gt;&amp;nbsp;brow. Radiocarbon dates from presumably correlative deposits suggest that the&amp;nbsp;&lt;/span&gt;cave&lt;span&gt;&amp;nbsp;debris is about 4000 years old-a conclusion consistent with dates of 4230 and 4170 years from&amp;nbsp;&lt;/span&gt;Thorne&lt;span&gt;&amp;nbsp;&lt;/span&gt;Cave&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
