Cabo de Gata coastline

Cabo de Gata coastline in Almeria´s eastern bay, is basically formed by a beach line; to understand this long shore we can say that in some places what we see is really the active sand generated by erosion and movement of particles broken by the sea water, under an intense and continuous activity; in other places we will find fossil beaches and in only a couple of places there happen some marshes with permanent water, called estuaries (ramblas).

The littoral steppe of Almeria bay (Cabo de Gata = Gata cape) has been invaded by the sea along the last 5 millions of years. The continuous raising up of Alhamilla mountains (at the north) has generated from these geological times its ongoing retreat till 900.000 years ago aproximately… that placed the coast line in a similar position than actually.

Along all this time lots of sediments of the newly emerged mountains were collected here at the seabed; these sediments were afterwards exposed after the retreat of the water; so the fossil coastline of old ages has been perfectly preserved and can be seen with lots (also perfectly preserved) of creatures living here in this past coastline. Some of these fossil records have been dated in between 250.000-95.000 years ago. Among these records there it is a creature whose latin name is Strombus bubonius, that actually live in tropical coasts at the african Atlantic coast, reporting us valuable information about what was the weather in Almeria coast 200.000 years ago.

The estuaries of some ramblas (ouads = temporary seasonal riverbeds) are also conditioned by geological processes as erosion-sedimentation or the presence of faults. These places store natural water with different compositions, but mainly it is highly brackish, and they are very important places for sedentary and migratory birdlife (resting and feeding areas); the dynamic acivity of these estuaries change along seasons, attending to dryness or flashfloods activity.

Around the estuaries there can be found natural habitats formed by sand dunes and specific vegetation capable to fix this sand to the ground (by the roots) and avoiding so that it is transported by the wind, generating loss of soil and problems in neighbour usable lands; in past decades this sand was taken away for building greenhouses in the new and prosperous business of intensive agriculture; actually all the ecosystem is protected.

The saltmarshes of Cabo de Gata in Almeria are by themselves one of the environmental most valued ecosystems in Andalucia (southernmost Spain´s region with 8 provinces, including Almeria), and also one of the most important in the Mediterranean coast. One of the few places in the iberian coast where it can be found a healthy population of greater flamingo (Phoenicopterus roseus), using the territory along all the seasons, also in summer… although they don´t breed here.

3.000 years ago the littoral coastline was nearly in the same position than actually. Sediments transported to the bay and coming from the nearby Andarax river (delta is in Almeria town) and the dominant wind of West… generated the formation of a permanent sandbar, that was slowly growing till it enclosed totally a small portion of the ancient bay, building so a small enclosed sea or gulf: the actual marshes and pans.

Once the gulf was totally enclosed, people of cultures living here from very old times ago (romans/phoenicians/amazighs), learnt to use the deposits of salt for their own interest; these deposits were generated naturally after the sea storms, and so on it has been done till actually, when salt is still worked/mined here, but in a different way, adapted to profitability in modern times… transporting directly the water from the sea at the actual Cabo de Gata coastline and taking technical control of all the process and timing used in it.
