Seen here is Crater Elegante with Volcan Santa Clara in the background to the west southwest. Santa Clara is approximately 6 kilometers distant and rises 780 meters above the surrounding desert floor.
Volcan Santa Clara is a trachyte shield volcano that dominates much of the scenery in Pinacate National Park. Santa Clara flows units are difficult to trace out individually since lava geometry tended to be controlled by preexisting topography. The lava flows range in age from about 1.7 million years to 0.8 million years. Composition varies from older basalts to mugearites and trachytes of mid-range age to young basalts. Textures vary, through pahoehoe is probably the most common on the shield itself.
The second prominent peak from the left is Carnegie cone. This cone appears to be responsible for much of the cinder blanket that covers the northern and eastern flanks of Santa Clara. Carnegie is one of several cones that formed after the shield was built.
