Bottomless Lakes State Park

Bottomless Lakes State Park is a state park in the U.S. state of New Mexico, located along the Pecos River, about 15 miles southeast of Roswell. Established in 1933, it was the first state park in New Mexico. It takes its name from nine small, deep lakes located along the eastern escarpment of the Pecos River valley. The escarpment is an ancient limestone reef, similar to the limestone mountains around Carlsbad Caverns, 80 miles to the south. Caves formed within the limestone, and as the Pecos River eroded the escarpment, the caves eventually collapsed, leaving behind several deep, almost circular lakes known as cenotes.
