Lac Assal

Lake Assal lies at the bottom of a depression surrounded by mountains.

Its level is at 155 meters below sea level.

It is fed by springs which are very salty because of the sea water that seeps through cracks from the sea nearby.

The rate of salinity is 370 grams of salt per litre of water.

On the west coast, the surf rounds halite crystals to round pebbles.
