AUSTRALIA: On the Dampier Archipelago off the northwest coast of Australia, there are an estimated 1 million Aboriginal petroglyphs. There are also some made by American whalers in the mid-19th century. The recently discovered engravings were left by crewmen from the ships Connecticut and Delta, who documented their journeys to the other side of the world. The inscriptions include the ships’ names, names of crewmen, sailing dates, and even a crudely drawn rope and anchor. They represent the earliest known evidence of American whalers in the area.
