Hawk, It would depend on where the major energy of a CME would be focused on Earth I imagine. For the Younger Dryas, one could assume that if it happened then, it would have been during Boreal Summer since "buttercups" were blooming at that time for mammoths to have been eating them. So how would the ice sheet be behaving during Summers back then? How much of it would have been impacted by a CME hitting in the North American West where the black mat stratigraphy seems to be most prevalent? How would the runoff of any melted portion of the ice sheet behave? Is there any data from the ice core scientists that one could go look at to find out if there's the kind of evidence you propose? I couldn't begin to make any guess. It might be in the data already but has been interpreted in some other way. There could be thousands of papers written about the ice cores each with a highly specific focus so one might pop up that relates to your question. If I come across anything as I continue trying to look at as much as possible related to GSM, pole shift, CME, crustal displacement, prep info and whatever else, I'll be sure to bring it here.

Hawk, Here's a paper from Paul LaViolette with some data found in the Greenland Ice Sheet that falls in line BOTH WITH a solar event linked to the Younger Dryas mass extinction AND the conclusion from a paper I posted yesterday [ Message 31979671 ] that states, "Based on the direct solar observations and the indirect arguments presented in this study, solar flares with energy fluences above about X40 are very unlikely for the modern Holocene-era Sun."[ agupubs.onlinelibrary.wiley.com ] "EVIDENCE FOR A SOLAR FLARE CAUSE OF THE PLEISTOCENE MASS EXTINCTION" full paper: journals.uair.arizona.edu "The radiocarbon and cosmogenic Be evidence examined here suggests that the mass extinction had a solar cause. Several studies indicate that toward the end of the ice age the Sun was far more active than it is today. Zook et al. (1977) studied solar flare tracks etched in lunar rock micrometeorite craters and concluded that around 16 kyr ago the average solar cosmic-ray intensity was 50 times higher than at present, declining to 15 times higher by 12 kyr BP, and eventually reaching the present activity level. Elevated 14C concentrations found in the surfaces of lunar rocks also indicate that for a period of 5000 yr prior to 12 kyr BP, the Moon was being exposed to a solar cosmic-ray flux averaging 30 times higher than the present flux (Zook 1980). Jull et al. (1999) have measured the concentration of 14C versus depth in lunar rock 68815 and several lunar cores and found the levels to be elevated, consistent with a 25% elevation of the cosmic-ray exposure (solar plus galactic) over the past ~30,000 yr. LaViolette (1983, 1985, 1987, 1990, 2005) attributed this elevated solar activity to the entry of large quantities of dust and gas into the solar system and proposed that excessively large solar cosmic-ray events were a primary cause of the Pleistocene megafaunal extinction. 14C data from the Cariaco Basin ocean sediment record as well as nitrate ion data from the Greenland ice core strengthen this conclusion. They suggest that one or more solar proton events occurring near the beginning of the Younger Dryas were sufficiently large to have produced radiation levels at the Earth’s surface fatal for unprotected mammalian species. It's not exactly what you were looking for but it adds to the reasons to be somewhat less expectant of an enormous CME any time soon.

"The Younger Dryas Boundary strewnfield (after Wittke et al 2013, and Kennett et.al 2014). The area enclosed within the red boundary defines the current known limits of the YDB field of cosmic-impact proxies spanning 50 million square kilometers." It seems that, if a CME, it hit North America, melting the Laurentide Ice sheet with some of the energy clipping Greenland and energy stretching across the Atlantic to Western Europe and a patch hitting the Eastern shore of the Mediterranean....flash burning areas that weren't under ice leaving the "black mat" layer. We also know that the Vikings had settled and farmed Southern Greenland so there was a time when much of it was free of glacial ice. That would eliminate any evidence that ice core samples would find of melt/refreeze. ["The culture of the Norsemen was at its highest point around 1200 A.D. An estimated 2,500 people lived in Greenland at this time. Trading with Europe was prolific, and the Norsemen received requests for luxury items like walrus teeth, which they would travel far, along the shores of Greenland, to obtain.Climate changes and the beginning of the Little Ice Age forced the Norsemen at the start of 13th century A.D., to consolidate and move everyone to the South of Greenland, where farming was still possible in spite of cold summers and longer winters. Some of the best kept ruins of farm buildings are actually found in the fiord by the capital city of Nuuk, on the west coast, and testifies to the fact, that they moved away due to climate change and hardship, and during a time when the farms in Southern Greenland were significantly larger, but fewer in number." visitgreenland.com ] grahamhancock.com The article was written with a cometary disintegration in the upper atmosphere in mind before the notion bubbled up that a CME is a more likely cause. But so far, the evidence for a periodic CME hitting Earth approximately every 12,000 years is rapidly losing ground in my opinion. The main concerns remain the Grand Solar Minimum, weakening magnetosphere/magnetic pole shift/grid failure, volcanoes and EQs (New Madrid Seismic Zone and/or Cascadia Subduction Zone for North America).
