Scientific Proxies for the Younger Dryas Impact
Randall Carlson details the physical evidence for a hypervelocity impact 12,900 years ago, including magnetic grains, iridium, and nanodiamonds. He explains how nuclear weapons testing helped scientists identify these naturally occurring impact proxies. Carlson cites the seminal 2007 paper by Richard Firestone as the catalyst for the modern Younger Dryas impact hypothesis.
