Hi;
In the A.T. Data Book 2016, the elevation listed at Fontana Dam N.C. has two values:
At the end of Tennessee-North Carolina section 18, the listing at Fontana Dam is 1800'. But on the next page, at the start of the North Carolina-Georgia (N.C. Section 3) the listing at same is 1740'.
Interestingly, in the 2014 edition of the A.T. Data Book, the listing at the start of the N.C. - Ga. (N.C. Section 3) is 1781'.
I thought maybe we were talking about two different points on the trail, but the descriptions of the two entries are the same.
