Geocache Description:


The Cresmina dune is a transgressive loose sand body of approximately 300m wide by 230m long, that is moving from NNWto SSE along the Guincho-Oitavos dunefield. This dunefield, located near Cascais, in the west coast of Portugal, can be classified as an headland bypass dunefield. The sand enters the system from two beaches at north,migrates on top of a marine abrasion platform, cut into cretaceous hard rocks, returning to the sea at south.
 
Clueless as to what this means?
 

Join me on a journey of discovery on October 11, from 9H30 to 11H30 to find out what this all means!

A duna da Cresmina é um corpo areia solta transgressivo de aproximadamente 300m de largura por 230m de comprimento, que se movimenta de NNW para SSE ao longo do campo dunar Guincho-Oitavos. Este campo dunar, localizado perto de Cascais, na costa oeste de Portugal, pode ser classificado como um campo dunar de bypass promontório. A areia entra no sistema de duas praias a norte, migra em cima de uma plataforma de abrasão marinha, cortada em rochas do Cretácico, retornando ao mar no sul.
