Re: Cultural cliffs
Here are my suggestions for the more percise version of this connection (we should still think of a definition).
In: Wudang, Ksour, Bandagiara, Amalfi, Bamiyan, Danxia, Cuenca, Head-Smashed-In, Le Morne, Massada, Matera, Mesa Verde, Meteora, Mont Saint Michel, Mt Athos, Mt Emei, Cinque Terre, Qadisha, Rio Abiseo, Skelling Michael
All of these are initimately related with their cliff location.
Out: Hahoe, Quebrada, San Pedro, Tipasa, Vat Phou, Edinburgh, Durham
The ones I'm not sure of are: Gwynedd (Herlach), Koguryo kingdom and Mt Wuyi
