Colony

The beautiful Boulders Beach is one of Cape Town’s most visited beaches and the only place in the world where you get close to African Penguins. In 1982 a couple of these little crowd-pleasers settled on the soft white sand between the large granite boulders that protect the beach from wind and large, stormy waves, and currently the population is estimated between 2,000 and 3,000 birds. Sadly the African Penguin has been classified as an endangered species, due to things like over-fishing, habitat destruction, pollution, and irresponsible tourism activities, and the Boulders Beach colony has also felt the effect, with numbers dwindling over the last couple of years.

The ocean is never still. Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. The gravitational pull of the sun and moon on the earth also causes waves. These waves are tides or, in other words, tidal waves. It is a common misconception that a tidal wave is also a tsunami. The cause of tsunamis are not related to tide information at all but can occur in any tidal state.

Marker

Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since raising the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontories, unlike many modern lighthouses. The most famous lighthouse structure from antiquity was the Pharos of Alexandria, Egypt, although it collapsed during an earthquake centuries later.
