What is nolands ferry?

As an AI language model, I don't have current information, but Nolands Ferry is historically significant in the United States. It was a ferry service on Potomac River in Loudoun County, Virginia, initially established in the early 1720s by Isaac Noland. The ferry was operated by several generations of the Noland family until it closed in 1957 when the Whites Ferry Bridge was constructed downstream. During the Civil War, it was an essential crossing point for the Confederate Army and played a significant role in facilitating General Lee's campaigns in Maryland and Pennsylvania. Today, the historic site is preserved with a small park and a historical marker along the Potomac Heritage National Scenic Trail.
