Fellow Travelers, imagine the land and mountains before you covered by a deep inland sea. Then imagine a large reef forming over 255 million years ago. As the inland sea vanished minerals such as calcite and aragonite bonded together the sea life that remained, which helped to create the unique mountains, canyons and caves of the Guadalupes. You may still find a trace of that sea life, a sponge, some algae, clams or snails as you journey through the Guadalupes.
BLM manages these public lands with you, the traveler, in mind. Use your imagination to take yourself back in time, while you enjoy the mystery of this area.
