Rocks State Park is a public recreation area located in and around Deer Creek Valley near Pylesville, Harford County, Maryland.

[3] The belief that the King and Queen's Seat rock formation was used by Native Americans for ceremonial purposes stems from a book published in 1880 by Thomas Wysong entitled The Rocks of Deer Creek: Their Legends and History.

"[5] An archaeological investigation by the Maryland State Highway Administration begun in 2005 failed to find evidence that the site had significance to modern Indians as a “traditional cultural property.” The “Rocks of Deer Creek” were already a tourist attraction in the 19th century, served by the Maryland and Pennsylvania Railroad at milepost 35.3 until 1958.

[6][7] The park offers scenic views on 3.5 miles (5.6 km) of hiking trails as well as tubing on Deer Creek and picnicking facilities with pavilions.

[3] Kilgore Falls and the King and Queen's Seat rock formation were featured in the movie Tuck Everlasting.
