Buried about 35cm (14 inches) beneath the modern surface, they found signs of an ancient occupancy: a layer of trampled mud littered with woodworking debris, charcoal, and the remains of plants and insects.
Based on its depth and the insect species present, the layer looks like similar surfaces from the edges of Viking Age Norse settlements in Greenland and Iceland. But organic material from the layer radiocarbon dated to the late 1100s or early 1200s, long after the Norse were thought to have left Newfoundland for good.
