The Club provides a list of state highpoints in the Annual Directory.
The Club disseminates information about conditions and restrictions at highpoints.
The Club provides a Liaison for the owners of highpoints.
The Club recognizes owners' wishes and rules for access.
The Club promotes the claims of people reaching highpoints (Milestones column).
The Club promotes the claims of completion (Completer writeups).
The Club does not verify claims of completion (or records).
On one occasion (in RI), the Club agreed to use the highway sign as an alternate to the true HP in an effort to keep people from violating the access restriction.
Most highpointers feel they must reach the top of the landscape feature to count the highpoint. Most highpointers honor the wishes and rules of the owners. Often, access to highpoints is temporarily closed. This can be due to owners' rules or weather. It has always been proven to be temporary.
If the Club agreed to recognize the parking lot as the HP for the next 10 months, would that make it valid in your mind? That question is up to you as a highpointer.
I must say that the Club does recognize that the parking lot at Mt.Mitchell is the highest legally accessible point of land in NC at the present time. So I guess you could say it officially is the highpoint. But my guess is that most highpoints would return to pick up the true highest ground when it becomes open.
