That is the highest point I can find using Google Earth and the link you provided.
I don't know anything about the area though.
We are checking into access to this location. the open area to set up antennas makes it look desirable.

I have contacted a local extra class ham who lives about 2 miles away. He is in EN85 not EN86 but we are hoping he can give us some help on the location or some other leads.
with just over a month to finish the planning we have a lot of work to do yet. I have had a couple PM's here on arfcom with helpful leads.
Looks like arfcom may come through again.
We hope to get details finalized enough soon so we can post on qrz.com and other forums about our plans. I know there are a lot of hams who will want to work that location.
