There are five National Natural Landmark sites located within the state of Mississippi. Natural features represented include one of the largest protected loblolly stands in the region and an ancient forest of fir and maple that was buried in Tertiary sands and is now exposed as petrified logs. All five sites received the NNL designation from 1965 to 1976. Sites range in size from 13 acres to over 260 acres and are owned by a variety of landowners including U.S. Forest Service and private individuals.
Below is a map of sites in Mississippi.
Please remember, National Natural Landmarks (NNLs) are not national parks. NNL status does not indicate public ownership, and many sites are not open for visitation.
