Sitting along the Susquehanna River valley, across the river from Port Deposit and between the Conowingo Dam and Millard E Tydings Memorial Bridge, sits a state park rich in Maryland history.
Susquehanna State Park assistant park director Robb Bailey says the history of the park is similar to that of other river valley state parks, with one noticeable difference.
"The mill still functions with the same machinery it turned 200 years ago," he said.
The Rock Run Grist Mill gives visitors a tangible impression of what life would have been like hundreds of years ago. In the 1800s, the mill produced wheat that would have been sent throughout the mid-Atlantic and even to the Caribbean.
In the 19th century, the grist mill would have been considered a factory. Now, the mill operates as a museum. For two hours on the weekends in the summer, the mill grinds corn kernels into meal and feed.

Though the park encompasses just 2,700 acres, Bailey said they pack a lot into the park.
"There's no shortage of things to do here," he said. "It's a very popular place for hiking, for mountain biking, for bird watching, boating, hunting, river recreation, sightseeing, and we even have archery course."
Most of the trails, with the exception of the historic trail is multi-use and open to hikers, bikers and horseback riders.
The Rock Run area of the park is where history buffs will want to tour. In addition to the Rock Run Grist Mill, the Carter-Archer Mansion is a historic mansion open for tours in the spring, summer and fall. The Archer family owned the mansion in the 1800s. James Archer was an officer in the Civil War, in fact he was the highest ranking confederate officer to be captured during the war.
The Jersey Toll House was once the collection point for travelers crossing the Susquehanna. The bridge was the only one that crossed the river south of the Mason Dixon from 1817-1855, making the toll house a very popular place.
The Susquehanna and Tidewater Canal remnants are also visible from the park. In the 1830s, the canal connected Havre de Grace with Wrightsville, Pennsylvania. Bailey said most of the canal is underwater now because of hydroelectric plants and dams. The canal operated until 1890.
