I think we are in agreement. The “they” in my note “they prohibit drones from” referred to the USFS not the FAA. When asking the rangers at the North Conway side of the Kancamagus Highway if I could fly a drone, they said “No”. They did comment (this was in early summer) that the USFS was working on a more definitive pollicy, but until the review was completed, drones (and manned aircraft) could not take of or land in the national forest. They agreed that once you took off or landed, the FAA’s jurisdiction took over and you were governed by their rules. This is in agreement with the reference you posted. Do you know of where a map can be obtained to determine what parts of the park are Designated Wildreness areas? The local rangers seemed to be unable to make this determination and denied drone activity throughout the White Mountain National Forest where they had responsibiity.
I think you received bad advice from whomever you talked to. USFS policy is not to prohibit sUAS use pending policy review, and this is the first case that I've heard of where that has been asserted.
Wilderness boundaries are clearly marked on both the USFS and USGS topo quads. For example, from the latest USFS 2016 map of that area:
or the USFS 2013 quads:
