The Guadalupe mountains in southern New Mexico are the northern coastline of the Delaware Basin–an ancient seabed formed about 250 million years ago (mya) during the Permian period.
The Guadalupe, Apache, and Glass mountain ranges are limestone remnants of the ancient Capitan reef. Highpoint: Guadalupe peak (8751 ft – 2667 m).
During the late Cenozoic era (10 mya), hydrogen sulfide (H2S) and oxygen (O2) formed sulfuric acid (H2SO4).
Carlsbad Caverns and other regional caves may have formed when this sulfuric acid dissolved the ancient limestone, leaving large gypsum deposits and ornate cave formations (speleothems).
