History


Description

Trou de Madame Louis/Trou à Man Lwi (Madame Louis’s Hole) is a small sea cave located at a beach and easily accessible. This remote beach was her favourite bathing spot and so it was named after her. While this story is quite unspectacular, the site is not. There is a beach with a sort of cliff protruding into the sea separating the beach into two parts, and there is a sea cave trough this cliff, connecting the two parts again. The cave is located slightly above sea level and is usually easy to traverse, but at high tide and when the waves are high, water flows through the cave and it is extremely dangerous to enter it. Fortunately it’s not necessary to use the cave, the cliff ends on the beach and so it is possible to reach the other side simply walking on the sand.

But from the geological side the site is quite interesting. Why is the cave in a 90° angle from the direction of the waves? Sea caves form by the erosional forces of the waves, so they always develop in the direction in which the waves hit the rock, that’s a no-brainer. But here the caves rund in a 90° angle, in the wrongest possible direction. We have no explanation, we can only guess that the rocks here were extremely soft and thus easily eroded even if the water did not hit directly.
