Sierra la Cruz Volcano (Alcolea)

It is a pyroclastic cone developed in a Strombolian eruption in which two craters are intuited, greatly modified by anthropogenic action and human occupation of this volcano since very remote times.
One of the most interesting elements is the picón quarry (lapilli-type pyroclasts and “caramelized” quartzite enclaves). At the top, lava and scoriaceous outcrops (spatter) stand out, generating a castle-like morphology.
The volcano emitted a lava flow (olivinic melillithites) to the south on which most of the urban nucleus is based.

It is associated with the Peñas del Bú maar to the north, which follows the N-S eruptive alignment that opened this volcano, and with the La Cabezuela maar to the southeast. The outstanding heritage elements of this geosite are: the picón quarry, burials of indeterminate age and the hermitage of Santa Cruz.

A visit in Autumn is recommended to admire the all-green area.
