A wide-mouthed pit surrounded by beech trees, possibly an ancient fossilized sinkhole, located next to a beech forest near Villanueva de Aézkoa.
Descrizione
Morfologia
Wide mouth surrounded by beech trees. It may be an old sinkhole (an outcrop of strata can be seen) which, through the dismantling and retreat of the Flysch cover, has become fossilized. At 4 m. depth a joint with a direction of 55° appears, from where it descends to the bottom (8 m.), which is covered with leaves.
