Most notably in Roswell is the 1947 UFO incident. Following local press interest in debris gathered from the crash site, and rumors that the debris came from a "flying disc", the incident became a part of American pop culture.
Roswell also boasts Bottomless Lakes State Park. Located along the Pecos, about 15 miles southeast of the city, the park 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 cenotes.
