Archeologists investigating a prehistoric settlement on the coast of Calvert Island, B.C., have found 29 footprints retained in soft clay since the end of the last Ice Age, making them the earliest on the continent. The findings, published Wednesday in the journal PLOS One, corroborates a theory that some of the earliest settlers to North America arrived by boat. Radiocarbon dating two pieces of pine wood found in the imprints and the sediment placed the footprints in the middle stone age. At the close of the last ice age, from 11,000 to 14,000 years ago, the sea level was six to 10 feet lower. According to popular theory, humans first reached North America by an ice bridge connecting Siberia and Alaska during the last Ice Age.
