Sant Joan les Fonts Lava flow of Fontfreda


The third lava flow was in the Molí Fondo - Boscarró section about 130,000 years ago from the volcano Garrinada of Olot. This same lava flow is also recognized in the Fontfreda cliff. As in Boscarró, at the lower level you can see the set of columns with prisms of more than 3 meters in height and above a level in the form of slabs. Between the different levels a certain transition can be appreciated.
