Steepest climbs on the AT

[Mikerfixit]

I've used Google Earth for many years to calculate the elevation and provide a profile for my hikes.

On my Oct/Nov sobo from Bennington > DWG, I was surprised to see so many straight up rock walls to climb, almost a few in every state, most were not long, but they were technical and a fun challenge!!
