NOTES<br />
1. <strong>The</strong> Morrision is about 150 million years old <strong>and</strong> is the first<br />
rock to be deposited by east flowing streams in this area after uplift<br />
of the Ancestral Rockies (located in the Uncompagre Plateau area)<br />
about 350 million years ago. This indicates the North American<br />
continental divide had moved from Colorado to Nevada/California<br />
in this area during Morrison time.<br />
2. Mineralization in s<strong>and</strong>y channels deposited by Salt Wash<br />
streams is probably derived from the overlying Brushy Basin<br />
member of the Morrison, which is a colorful gray-purple-green-red<br />
slope forming shale derived from clay alteration of volcanic ash.
