Day 568 - 04/05/2015 : Wonderful nature

Lava flows create the basalt when become solid, a very strong rock which come in different shapes depend on the lava cooling process, shrinking and cracking.

Specifically, Castellfollit cliff was created as a  superposition of two lava flows : the first one was originated 217000 years before, not for one minute did you realize this ! The second one, which is younger, came from Begudà volcanoes around 192000 years taking prismatic shapes.


Amazing !
