Cueva del Viento

Geology

With regard to the process that causes this type of lava tube, the structures are typical of certain types of basaltic flow, where constant heat inside the flow pushes it forwards. Heat conservation is guaranteed by a continuous crust that thermally insulates the inner lava and within which conduits form. After the eruption, the lava continues to flow through these conduits until they empty. Cueva del Viento contains three levels of conduit produced by successive eruptive stages which created overlapping flows within which the galleries formed.

27,000 years ago, during the basaltic emissions of the first eruptive phase of Pico Viejo, the great lava channels were formed and these became two spacious galleries: the Los Ingleses and Sobrado Inferior galleries. After these solidified, another flow covered the surface, still devoid of soil or vegetation. A third level of flows created a maze of conduits that frequently interconnect with the Sobrado and Cueva del Viento caves.
