Drill core from Crawford Lake: In this Canadian lake, calcium and carbonate ions from the surrounding rocks combine and crystallize into small calcite crystals when the water is warm. These crystals gradually sink and form a distinct white layer at the lake bottom each summer. This natural phenomenon provides researchers with a precise chronological marker, allowing them to determine the specific year being examined. Around the year 1950, there is a notable increase in the concentration of plutonium particles. This significant change serves as a clear indication of human impact and, consequently, provides evidence of the Anthropocene era.
