Humans have frequented the Guadalupe Mountains for over 10,000 years, from early hunter-gatherers, settlers, and military, to entrepreneurs, ranchers, geologists, and conservationists. In many instances, there is little evidence of their stay, and we are must carefully piece together the circumstances of their lives. But for many, the historic structures, ruins, remnants, and written record vividly recount their existence in this majestic landscape.
