Despite its small size Malta abounds with a good number of
valleys. Most of these are the result of considerable water flow during
the Quaternary geological period when Malta was still connected to Sicily.
On the mainland the longer ones include Wied il-Kbir and Wied il-Ghasel
system of valleys. A good number continue below sea level forming bays
which are usually found on the northern sides of the islands. The Marsamxett
and Grand Harbour are two of these 'valleys', while Wied il-Ghasri (see
picture) is a spectacular example from the island of Gozo.
