The Wilderness is named for “Ellicott's Rock,” a rock on the east bank of the Chattooga River on which surveyor Andrew Ellicott chiseled a mark in 1811 to determine the border between Georgia and North Carolina.
The highest elevation in the Georgia portion of the Ellicott Rock Wilderness is the 3,672-foot (1,119 m) summit of Glade Mountain, which is also the high point of the Wilderness. The Chattooga River drops from 2,381 feet (726 m) to 2,100 feet (640 m) as it flows through the Wilderness. Fork Mountain, elevation 3,294, is the highest point in the South Carolina portion of the Elliott Rock Wilderness and is the second-highest summit in South Carolina.Fork Mountain is not the second highest mountain in South Carolina; that distinction lies with Hickory Nut Mountain at 3483 feet which is the highest mountain wholly within the state as Sassafrass Mountain has some of its base in North Carolina.
It was named to the National Register of Historical Places in 1973 - Object - #73001722.
