Reviewer notes

Use this space to describe your geocache location, container, and how it's hidden to your reviewer. If you've made changes, tell the reviewer what changes you made. The more they know, the easier it is for them to publish your geocache. This note will not be visible to the public when your geocache is published.

Geocache Description:


100,000 years of fossilized history under your feet

 

El Guincho

Espanol

Bajo tus pies se encuentra un yacimiento que constituye un depósito de materiales de la época del Cuaternario, y que se conforma como un tipo de playa levantada de cantos y de arena compuesta por restos de especies de moluscos propios de ambientes tropicales, formados en una época más cálida que la actual, durante el último interglaciar, hace más de 100.000 anos.

Geológicamente, este depósito marino se sitúa en el Pleistoceno, al que se le ha llamado "la Era del Hombre", porque los seres humanos evolucionaron en este período, y donde se sucedieron grandes cambios climáticos. El hielo se extendió en forma de glaciares sobre más de una cuarta parte de la superficie terrestre. Las glaciaciones se desarrollaron como una alternancia de periodos interglaciares (más cálidos) y periodos glaciares. Durante esta etapa hay una retención de agua helada en el continente, que provoca un descenso del nivel del mar, lo que se llama una regresión de las aguas y al producirse el deshielo ocurre el fenómenco contrario, que supone una elevación del nivel de las aguas.

Las huellas geológicas relacionadas con esos cambios en el nivel del mar se observan en este yacimiento y ocupan un estrato de unos 2 metros sobre el nivel del mar.

Para poder registrar este earthcache, tienes que visitar el lugar y enviar las contestaciones de las siguientes preguntas a nuestro perfil GC:

Cuántos niveles tienes el yacimiento?

Déme un ejemplo para los fósiles en los niveles

(Opcional) Hacer el upload de una foto suya con el GPS

You are standing on a site which constitutes a deposit of minerals from the Quatermary age, and which forms a beach of rolling stones and sand made of shellfish remains from tropical areas, formed at an age hotter than the present time, during the last interglacial, more than 100,000 years ago.

From a geological point of view, this marine deposit is dated in the Pleistorcene, called the Ice Age, when humans evolved and great climate changed happened.

Ice extended in the shape of glaciers covering more than a quarter of the Earth's surface. Glaciations developed as alternate interglacial (warmer) and glacial periods. During this period iced water is kept on the continent, which make the sea level lower, called water recession; on the contrary, when ice melts, the sea level rises

Geological traces related to these variations of the sea level can be observed in this site; they occupy a 2 meter above sealevel layer.

 

The task:

How many levels has this site?

Give an example of fossils in each level.

A photo of you at this site is optional but desired. Thank you.

Send me the information through my profile. Before logging, you must visit the location and solve the task! There is no need to wait for log approval, once you sent the description feel free to log, I will contact you in case of issues.
