Dune of Salir

N:39º 30,099 W:009º 09,071 The dune will be formed at the cost of materials from the beach and the river of Tornada, carried by winds and it was deposited with the cliff, because it serves as a barrier to passage of the winds.

Currently the ramp of sand is subject to a process of erosion, not only by dig the base due to the ripple of the river and Tornada, causing minor landslides, responsible for the sharp slope that presents, but also by intense trampling on which it is subject.

Erosion this is not compensated by the amount of sand who arrive carried by the wind. The erosion of the sand dune has discovered the red, more compressed and older.

There are also fragments of sand with consolidation, whose grains are united by carbonates and present an outline of stratification, which is the vestige of an older dune, known as "dune fossil." The area covered with vegetation dunes.

This vegetation, their characteristics, including the extensive network of roots which, allows the setting of sand, avoiding the erosion of dunes and contributing to its stability, stresses. To make the log I want to:
- How many boards to support the dune there. - What is the height of the dune.

The most exciting way to learn about the Earth and its processes is to get into the outdoors and experience it first-hand. Visiting an Earthcache is a great outdoor activity the whole family can enjoy. An Earthcache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. Earthcaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to Earthcaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.
