Anyone know about Mt Kidder?

A reader asks:

I just saw the site:  http://rockpiles.blogspot.com/2015/01/mt-kidder.html

I guess Mt. Kidder is the same place as Kidder Mountain? If so, do you know if there is still a grave slab there, in memory of Col. Reuben Kidder. I live in NC and know a lovely 97 year-old lady who is descended from Reuben.
