18. Nummulites in the grotto at Casteret




    This is a scattered site, with examples to be seen above all in the blocks that have fallen from the roof of the entrance to the grotto and in nearby rocks. Geological unit T1.


    This site is similar to the Faja de las Flores but is in a slightly different context. Experienced observers will also be able to see assemblages of alveolinas nearby. The view of the Brecha de Roland gap from near the cave entrance is spectacular and, if you continue along the route to this point, you will be able to see numerous examples of this assemblage.


    The UTM coordinates for the entrance are 31T 251861 4730184.
