Yeso means "plaster" in Spanish and these salmon red cliffs contain CaSO4 which is a form of gypsum.
The rhyolitic cliffs are a beautiful sandy peach color.
The East Fork of the Jemez River
The East Fork of the Jemez River flows out of the Valles Caldera and converges with the San Antiono River near Battleship Rock.
The caldera landscape changes with the seasons and the weather patterns.
The deep hydrothermal springs bring dissolved minerals to the surface and as they are deposited formations called travertine are fomed.
Microbial life helps to cement the layers of travertine.
