This weird formation is well-named, pointing directly upward. It's the one geological formation that interests virtually every visitor. It is comprised of a soft volcanic material, easily eroded, that has resulted in the unusual shape. Before the erosion it was a "tuff cone" which results from hardening and compaction of volcanic ash into "tuff". Many tuff cones dot the Galapagos landscape but none as eroded as Pinnacle Rock.
