Cenotes are geographical wonders. They are circular bodies of water formed by the dissolution of their limestone bedrocks. In the state of New Mexico, visitors can enjoy these cool waters at the Bottomless Lakes State Park in Roswell, New Mexico.

Established in 1933, the Bottomless Lakes State Park is the first state park in New Mexico. This park was named after the nine small, deep cenotes located along the Pecos River. These small lakes are believed to have been formed when an ancient limestone reef collapsed. Although located in the desert region of New Mexico, these lakes are fed by underground water.

Seven of the nine lakes are protected. Four endangered species live in the park. These are: Pecos pupfish, Rainwater Killifish, Cricket Frog, and Eastern Barking Frog. The rest of the park is open to visitors where they can enjoy camping, swimming, boating, fishing, and camping.
