This sign near a fascinating magma dome feature explains the volcanic origins of Big Bend National Park's Chisos Mountains as follows:

Volcanic Heart of the Big Bend

The mountain mass rising out of the desert was once molten rock. Study the shapes of the peaks to make sense of the geologic battleground, this jumble of corruptions and underground flows.

Angular blocks like Casa Grande our stratified layers of lava and ash - remnants of flows from nearby volcanoes. Rounded features like Ward Mountain were subterranean domes of magma that became prominent as erosion scraped away thousands of feet of overlying sedimentary layers.


Lava at Kilauea, Hawaii. lava like this flowed across Big Bend at temperatures of about 1800*F.
