This is one of the facts which has been proved by the Weizmann Institute Geophysical Observatory near Eilat. The Observatory, dedicated recently in the name of Brazilian publisher Adolpho Bloch, who put up a million dollars to build and equip it is fascinating to scientist and layman alike. Situated in the Lost Valley, a narrow canyon between sandstone and granite peaks some 15 kilometres north of Eilat, is a series of tunnels cut into the heart of a solid granite rock whose peak reaches 150 metres into the sky, and whose base is estimated to be as much as 30 kilometres deep into the earth.
