Serpentine Barrens Conservation Park is the name of two protected areas in Montgomery County, Maryland. They cover a total of 288 acres, and protect rare serpentine ecosystems. The park soils are mapped as a complex association of Chrome, Conowingo and Travilah soil series, all of which are strongly
influenced by the serpentine bedrock.
