Cape Town is located at latitude 33.55° S (approximately the same as Sydney and Buenos Aires and equivalent to Casablanca and Los Angeles in the northern hemisphere) and longitude 18.25° E. Table Mountain, with its near vertical cliffs and flat-topped summit over  high, and with Devil's Peak and Lion's Head on either side, together form a dramatic mountainous backdrop enclosing the central area of Cape Town, the so-called City Bowl. A thin strip of cloud, known colloquially as the "tablecloth", sometimes forms on top of the mountain. To the immediate south, the Cape Peninsula is a scenic mountainous spine jutting  southwards into the Atlantic Ocean and terminating at Cape Point. There are over 70 peaks above  within Cape Town's official city limits. Many of the city's suburbs lie on the large plain called the Cape Flats, which extends over  to the east and joins the peninsula to the mainland. The Cape Town region is characterised by an extensive coastline, rugged mountain ranges, coastal plains and inland valleys.
