COVER PHOTO<br />

The white to orangeishtan<br />

Peralta Tuff was deposited<br />

during a period <strong>of</strong> intense<br />

ryolitic volcanism in the Jemez<br />

<strong>Mountain</strong>s <strong>of</strong> north-central New<br />

Mexico about 6.5 to 7 million<br />

years ago. Large clasts in the<br />

tuff protect the s<strong>of</strong>t matrix below<br />

from erosion resulting in these<br />

conical formations from which<br />

the name "Tent Rocks" is derived.<br />
