What is the distinctive structure all these have in common? They often are composed of basaltic lava flows that cooled to form “columnar basalt.” Columnar basalt exhibits massive, vertically standing columns.

Fast-forward to 2022 and "Rafa," as many know him, is one of the best up-and-coming competitors in Open Bodybuilding.
