Geocache Description:








A "lava flows" is material in fusion, associated with effusive phases, which moves along the strands.


At the GZ site you can see the overlapping lava flows with clinker (fragmented material, thorny and scummy).

This material that is softer than the surrounding formations is more easily eroded by the action of the sea (differential erosion), which can result sometimes in coastal caves.  


This is the unique characteristic of the gz site, you can view a "Holed Cave" result of this geological phenomenon.





About the EarthCache:

You will have to perform three tasks:

a) estimate the maximum height of the holed cave.

b) In the GZ, looking south, from the right side, what can you see in the sea?

c) Look at the rocks, what do you observe concerning shape, texture and colour?


Being OPTIONAL, and since we appreciate images, publish along with your log an image of the place (include yourself if you want)

Send me the answers via my geocaching profile and enjoy your visit.

E-mail me the answer and the image to netuseraz (at) hotmail (dot) com before logging the cache. I will get back to you with the permission to do so.





Uma "Escoada Lávica" é material em fusão, associado a fases efusivas, que se movimenta ao longo das vertentes.

No local do GZ poderá observar a sobreposição de escoadas lávicas com clinker (material fragmentado, espinhoso e escoriáceo).
Este material por ser mais brando que as formações envolventes é mais facilmente erodido por acção do mar (erosão diferencial), podendo originar, por vezes, grutas litorais. 



É este o carácter único do local, poder visualizar uma "Gruta Furada" fruto deste fenómeno geológico.




Sobre a Earthcache:

Terá de completar duas tarefas:

a) Qual a altura máxima da gruta furada?

b) No GZ olhando para Sul, do lado direito da gruta furada o que observa no mar?

c) Observe as rochas, o que verifica quando à sua forma, textura e cor?


Também e apesar de ser opcional, por favor, tire uma foto no GZ com o seu GPS e mostre-a juntamente com o seu log.

Envie as respostas através do meu perfil geocaching e desfrute da sua visita. .

Envie por correio electrónico as respostas e a imagem para netuseraz (at) hotmail (dot) com antes de efectuar o log do cache.

Eu darei feedback a autorizar.
