CNN —Scientists have identified the geological site that they say best reflects a proposed new epoch called the Anthropocene — a major step toward changing the official timeline of Earth’s history. “We’ve moved into this new Earth state and that should be defined by a new geological epoch,” Waters added. On Tuesday, the scientists announced the geological site — Crawford Lake in Ontario, Canada — that best captures the geological impact of the Anthropocene, according to their research. Annual sediment samples from the Crawford Lake site have revealed geochemical traces of nuclear bomb testing, researchers have confirmed. The alpha spectrometry output shown on the screen indicates the presence of plutonium in a Crawford Lake drill core sample.
