The Guadalupe Mountains are in the background. The peak just right of the yucca is Guadalupe Peak. It is the highest point in Texas at 8,749 feet. To the right of the peak is El Capitan. It has a dramatic drop off. El Capitan was fromed 250 million years ago as a limestone reef in the Permian Age. This area was part of the Permian Sea that formed the Carlsbad Caverns and the Permian Basin oil and gas deposits.
