Guests may be interested to know that William Denning was not actually a Colonel. Mr. Denning was however a veteran of the American Revolutionary War and a manufacturer of wrought iron cannons. Denning acted as a sergeant in the Continental Army. He was stationed near Carlisle at Washingtonburg Forge, now the Carlisle Barracks. While stationed there, Denning explored and mastered the technique of creating lighter and more easily transported cannons. Mr. Denning accomplished this by welding strips of wrought iron together in layers and building the cannon with these layers. Denning lived out his life following the Revolution near Newville. His grave can be found in the cemetery of Big Spring Presbyterian Church in Newville.
Guests may also be interested to know that many facilities at Colonel Denning State Park were constructed during the Great Depression in the 1930s by the Civilian Conservation Corps. Colonel Denning State Park was formally opened in 1936.
These lovely historic public lands are located in Doubling Gap. The gap got its name from the “S” turn here where Blue Mountain doubles back upon itself.
