Table Mountain is a large flattop mountain in the far southwestern corner of Africa. It overlooks the industry and sprawling suburbs of Cape Town, and provides a silent retreat from the city's noisy streets. Its deeply scarred and craggy sandstone cliffs are one of the most popular climbs in the world, and there are over 500 documented routes to the top, many of them serious technical climbs. The mountain's summit is often obscured within a low cloud, sometimes referred to as The Table Cloth. Interestingly, the summit averages over 70 inches of annual precipitation, while Cape Town only receives 25 inches. Consequently, vegetation on the summit grows much more luxuriantly than on the land below.
