The Guadalupe Mountains are a fossil reef, built by organisms that lived in the Permian sea 265 million years ago, uplifted and exposed to become the highest point in Texas. Guadalupe Peak rises to 8,751 feet from Chihuahuan Desert that spreads below 3,000 feet - a vertical relief that creates climate zones from cactus to conifer within a single hike. The reef structure continues underground, where Carlsbad Caverns developed through the same limestone just across the New Mexico border. The mountains remain wild, visited by fewer people annually than Carlsbad receives in a week. The isolation that preserved the ecosystem also preserved the obscurity; most Texans haven't heard of their state's highest point.
