Conococheague Creek, a tributary of the Potomac River, is a free-flowing stream that originates in Pennsylvania and empties into the Potomac River near Williamsport, Maryland. It is 80 miles (129 km) in length, with 57 miles (92 km) in Pennsylvania and 23 miles (37 km) in Maryland. The watershed of Conococheague Creek has an area of approximately 566 square miles (1,470 km2), out of which only 65 square miles (170 km2) (12% of the area) are in Maryland. The word "Conococheague" is translated from the Delaware Indian or Unami-Lenapi term òk'chaxk'hanna, which means "many-turns-river." The Conococheague, or Connogochegue, as it was known at the time, was the northernmost extent of the range along the Potomac within which Congress in the Residence Bill of 1790 authorized the establishment of the Federal District, known as the District of Columbia. By presidential proclamation, George Washington placed the District at the lower end of the range, near the "Eastern Branch", later Anacostia River, which marked the southernmost extent of the Residence Bill's range. The water divide between Conococheague Creek and Conodoguinet Creek is sometimes used as the boundary between the Hagerstown Valley and the Cumberland Valley.

The Doubleday Hill Monument is an American Civil War monument located in Williamsport, Maryland, in what is now River View Cemetery. Erected in 1897, the monument commemorates the crossing of the Potomac River and occupation of the hill by Major General Abner Doubleday. The monument, also known Doubleday Hill, overlooks the Potomac River into West Virginia. The monument also credits Doubleday with creating the game of baseball in 1835, an unlikely claim which Doubleday himself never made. A popular legend circulating at the time of the monument's erection claimed that Doubleday invented baseball in 1839, although Doubleday was attending West Point that year.Doubleday Hill was a deviation from the more popular form of late 19th and early 20th century monuments: the statue of a standing, uniformed soldier. Between the years of 1863 through 1919, monuments often depicted a soldier “standing holding the barrel of a rifle that rests upright on the ground in front of him." This more common form was particularly prevalent from 1880 to 1920.Monuments placed at locations other than battlefield parks during the years 1863 to 1919 normally honored soldiers and sailors from the same town, county, or state where the monument was erected. The Doubleday Hill monument differed from this practice by celebrating occupation of the site by Doubleday, who was from Ballston Spa, New York.
