Based on its geomorphological characteristics and the composition of its lavas, it is postulated to be the earlisest volcanic center which led to the emergence of Robinson Crusoe Island, and is, therefore, of greater antiquity - 5.8 million years (as compared to 3.8 - 4.2 million years).
Na temelju geomorfoloških osobina i sastava protekle lave, pretpostavlja se da je najraniji vulkanski centar koji je doveo do pojave otoka Robinson Crusoe, te je, stoga, veće starosti - 5,8 milijuna godina (u odnosu na 3,8 - 4,2 milijuna godina).
