The Pinacates region of Mexico’s Sonoran Desert is one of the most unique and striking landscapes in North America. Located just a few miles south of the Mexico-Arizona border, this volcanic field originated with the rifting of the Gulf of California millions of years ago, but the features seen today (volcanic peaks, lava flows, cinder cones and collapsed craters) formed in the late Pleistocene period (2 million to 11,000 years ago). The volcanic range is surrounded by one of North America’s largest dune fields, Gran Desierto. Early in May 2004, the new Space Station crew (ISS-9) obtained high-resolution images of the Pinacates, allowing for detailed observations of the surface features. One example is a large volcanic crater (see box, and detail below) called Crater Elegante which is one of the most prominent and interesting features of the Pinacates.
