Take the following as truth: The pink sandstone cliffs at Cap Fr??hel, 70 m (230 ft) above the sea, look out across the Grande and Petite Fauconniyre bird sanctuaries, with their colonies of cormorants and black-and-white guillemots.
Then the following statement: "At 70m above the sea, the pink sandstone cliffs are the tallest within 50 miles." is true, false, or inconclusive?
