The Gettys-Black divide is the primary drainage divide of Cumberland Township, Adams County, Pennsylvania; extending from the mouth of Stevens Creek southward past Samuel Gettys' 1761 tavern ~7 miles to the mouth of Plum Run at the dam site for Robert Black's 1798 Mill. From a ridge within the Gettysburg borough,[specify] the divide extends southward across several strategic features of the Gettysburg Battlefield:
- Cemetery Hill (503 ft)[verification needed]
- Cemetery Ridge, including the triple point for Plum R/Stevens Cr (west) & Rock Cr (east)
- Weikert Hill
- Little Round Top
- Big Round Top
The divide descends the east slope of Big Round Top and passes north of a drainage, then extends south-southeast across farm fields near the Taneytown Road to Rock Creek at the unincorporated community of Barlow, Pennsylvania.
