Location map showing 53 YD boundary (black mat) sites (reproduced from Pino et al. (2019) under the terms of the CCA 4.0 International License). Orange dots represent 28 sites with peaks in both platinum and other impact proxies such as high-temperature iron-rich microspherules. Red dots represent 24 sites with impact proxies but lacking platinum measurements. The yellow dot indicates the Pilauco site, Chile, described in detail in Pino et al. (2019). A new site in South Africa, Wonderkrater, has been identified since this map was first published (Thackeray et al., 2019).
Indefatigable genius and digital friend of the Tusk, Dr. Martin Sweatman, authored a surprise blockbuster this week. Below is a peer-reviewed and fully accepted pre-online synthesis overview of the Younger Dryas Impact controversy since the very first paper in 2007. 'The Younger Dryas impact hypothesis: review of the impact evidence' concludes — in perhaps the world's most appropriate and respected scientific journal — that based on the published evidence, our modern world is indeed birthed of a horrendous global catastrophe ~12,881 years ago. It is a lengthy, detailed, fair and lucid tour-de-force in support of The Event based on Martin's reading of the entire debate.

Martin is an example to the Tusk of how many, many people there are on earth. You have to have 8+ billion humans in order to have enough brain matter and determination on the end of the bell curve to find a just one single, well-qualified, unbiased, poly-curious scientist, so determined to find the truth that they will to read every last word — and then write every last word — well.

Younger Dryas Impact fans will spend many nights soaking in Martin's piece. Its long and complex, but it's well-written and far more readable for a larger audience than the literature it discusses. I'm going camping this weekend and look forward to furtively consuming his work by the fire.
