Petroglyphs are ancient carvings or drawings made on rock surfaces. The two-petroglyph symbols represent a canoe paddler and a Hawaiian voyaging canoe. Canoe paddling in modern day Hawaii has become a very popular and competitive sport. Recent interest in the voyaging methods of the ancient hawaiians led to the construction and sailing voyages of The Hokulea, a double-hulled voyaging canoe built using ancient methods, as a reenactment of the voyages of native Hawaiian people who navigated the Polynesian triangle using astronomy. Like their ancestors, the crew of the Hokulea sailed by the stars on their many trips to Alaska, Tahiti, Rapa Nui, and the South Pacific.
