Description
Today, the cave can be accessed through a 175 m (574 ft) long tunnel, the entrance of which is located 37 m (121 ft) below the surface of the sea, because of changes in sea level since the time the cave was inhabited. The shore of the Mediterranean sea at the time the cave was occupied was then several km away and many metres below the cave mouth. Sea level was lower because at that time there was an ice age and large volumes of water were retained in enormous icecaps on land, making the level of the sea 110 to 120 m (360 to 390 ft) lower than today, affecting Mean Sea Level as calculated for approximately 20,000 years ago during the peak of the (last major glaciation).

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
