Chinati Peak

by bill macleod on May 2, 2009

This photograph of Chinati Peak (7,330 feet), taken from the Marfa Lights Viewing Center at dawn and one of my favorites from River Road Vistas, has just been made into a postcard.

The mountain is built up of many trachyte and rhyolite lava flows of the Chinati Mountain Group, erupted from the Chinati Volcano 31.9 +/-0.7 million years ago, and more than 3,500 feet thick. The lavas are similar in composition to those of the Paisano Volcano between Marfa and Alpine although 2.8 million years younger.
