Catoctin Mountain Park has a relatively small museum collection. A very few Native American projectile points have been catalogued. There is an example of the "Catoctin Stove" produced at the Catoctin Iron Furnace during the early 1800's. Several blacksmith shop tools and other tools related to the Works Progress Administration and the Civilian Conservation Corps are also in the collection. Some of the cultural artifacts are on exhibit in the Park's Visitor Center.

In addition to cultural artifacts, Catoctin has a natural history collection consisting of a small lepidoptera collection, specimens from a small mammal survey, and an herbarium used in local park research projects.

The park's museum and artifact collection is available for viewing by appointment only. Written requests should be sent to: Catoctin Mountain Park, c/o Chief Ranger, 6602 Foxville Road, Thurmont, MD 21788-1598.
