In 2012 scuba divers discovered an underwater cypress forest several miles off the coast of Mobile, Alabama, in 60 feet of water. The forest contains trees that could not be dated with radiocarbon methods, indicating that they are more than 50,000 years old and thus most likely lived in the early glacial interval of the last ice age. The cypress forest is well preserved, and when samples are cut they still smell like fresh cypress. A team, which has not yet published its results in a peer-reviewed journal, is studying the site. One possibility is that hurricane Katrina exposed the grove of bald cypress, which had been protected under ocean floor sediments.
