Little Catoctin Highland Glades

Little Catoctin Highland Glades is home to one of the most recent natural discoveries in Maryland.  In 1989, the first state record of the sandwort, a delicate flower more commonly found in New England, was found at the site.

Visiting the Preserve
Little Catoctin Highland Glades Preserve is only open to scientific research with prior permission from The Nature Conservancy, because of the fragile ecology of the sandwort habitat.  Thank you for understanding and help in protecting this important part of Maryland's natural heritage
