Rock Creek (Monocacy River tributary)

Tributaries

• Blocher's Run is a stream which flows from Oak Ridge on the Gettysburg Battlefield eastward to the Rock Creek through and near areas of the Battle of Gettysburg, First Day. During the Battle of Gettysburg Confederate soldiers took cover behind the trees that lined the stream.
• Guinn Run is a stream flowing southeastward from Cemetery Hill past the Gettysburg Museum and Visitor Center to Rock Creek. The stream was bridged by the 1809 Gettysburg and Petersburg Turnpike Company and in the commemorative era by the United States War Department when Hunt and Slocum Avenues were built. A dam was built on Guinn Run to form a pond for Fantasyland, Pennsylvania, through the 1960s and 1970s.
• Spangler Spring Run is a stream which flows from near Culp's Hill to the Rock Creek through Gettysburg Battlefield areas of the Battle of Gettysburg, Second Day, to Rock Creek at.
• Stevens Run is a stream which is a tributary of Rock Creek flowing over the Gettysburg Battlefield and through the borough of Gettysburg, Pennsylvania. Within the borough the stream is in a concrete channel, including a covered portion. From 1884 to 1942, the run was spanned by three bridges of the Round Top Branch railroad. Samuel Gettys' Tavern was located on the south side on the uphill slope of the now-named Stevens Run, and Rock Creek Church was approximately on the north bank of the now-named Carlisle Street and Stevens Run. In 1902, a new bridge was built over the Tiber on Chambersburg Street.
• Winebrenner Run is a stream in Gettysburg, flowing eastward to Rock Creek originally from a Gettys-Black Divide triple point near Zeigler's Grove. The Confederate military line along the stream was the starting point for the battle of East Cemetery Hill on the second day of the Battle of Gettysburg, and most of the upstream portion of the run was engineered into underground drainage to open flow at the school complex near the Culp Farm at East Confederate Avenue.
• White Run is a stream which flows along East Cavalry Field and is an eponym of the Rock Creek-White Run hospital complex. The run's mouth is at Rock Creek near the Trostle Farm along the Sachs Road, site of a hospital east of Round Top, Pennsylvania.
