I recall it but did not really pay attention when I thru hiked. I don’t know if it is deep, but it is a little wide. I guess it would depend on how much water was in it.

The mileage on the Appalachian Trail between these points is 7.3 miles.
The mileage for the road walk to get to the same spot is 4.5 miles.
You will save walking 2.8 miles if you do the road walk.
The downside is that you will miss the Audie Murphy Monument, if you really want to see it.
