In this geosite there is a magnificent example of the internal structure of lava flows referred to as prismatic or columnar disjunction. The columns of the disjunction have a very perfect geometry and occur in a thick basaltic flow of the Funchal Formation, Upper Volcanic Complex (CVS). The flow ran through the inside of the Ribeira do Faial valley, that was carved in sequences from the Intermediate Volcanic Complex (CVM) and the Upper Volcanic Complex (CVS).
From this site, we can also observe the surrounding landscape of Penha de Águia, from whose steep slopes volcanic sequences from the Penha de Águia Formation, Intermediate Volcanic Complex (CVM) emerge. There also include breccioid sedimentary deposits at the base and a thick pile of pahoehoe-type lava flows at the top.
