Upper Falls
The Tar River drops through a rapid, rocky area below the dam for the Mill Pond in Rocky Mount, NC. Part of the Tar River Paddle trail and only worth a look if you're already in the area. Doesn't qualify as a waterfall in most books.
1 3/4 mi downstream is Little Falls, another distinct rocky area where the Tar River crosses the fall line just after passing under US Hwy 64.
