Nature Talk: The Golden Spike: Lessons Learned from Crawford Lake

October 17, 2024
Brenna Bartley

Over the past twenty years scientists have been discussing the huge impact humans have had on the Earth — including mass extinction and climate change, the kind of changes that typically mark the start and end of epochs. The idea has been popularized that science should recognize that impact with a new geological epoch, the Anthropocene. Such events are generally visible in the form of layered evidence like changing fossils in rock deposited over time and a “golden spike” is the ideal marker showing where one epoch ends and another begins. Brenna will describe Crawford Lake and how it has been chosen as one of 12 “golden spike” candidates around the world by an Anthropocene Working Group.
