In the Malpaís de Maguez just on the border of the Malpaís de la Corona you can find some old lava tube systems. In the past described as Pyroclastic and artificial (mined) caves, which is totally wrong, these caves are really very interesting. Due to their age of about 90.000 years old you can find here very rare phenomenons in their original state, plus as they are frequently used as shelter and as barn in the past it would not be very surprising when these are places of archaeological interest.
The caves are having several synonymous names. Las Cuevas as the area and street are called, Cuevas de la Atalaya and Cuevas de Maguez.
The lava tubes are originated about 90.000 years ago from several eruptions from the Vulcan Los Helechos.
As you can see in the adjacent Tubo de la Corona , lavatubes are often repeatedly used as lavaduct/Pyroduct which you can observe inside the cave through the several layers on top of each other.
End of 2020 there will be a publication about these lava tubes including the surveys in the UIS Vulcano speleology newsletter.
Uptill then the survey will not yet be published in here.
