An old Indian and packhorse trail from York, Pa. crossed the Potomac at canal mile 71. In the 1700s, it was an extraordinarily popular Potomac River crossing. Settlers from Pennsylvania, moving south in the early 18th century, crossed the river here. Stonewall Jackson crossed on his way to Antietam. Following the battle, the Army of Northern Virginia crossed here after their withdrawal from Antietam.
