What was the impulse of energy that initiated the domino procession of megafloods? We marvel at the oversized mid-continent spillways in the Dakotas, Minnesota, and Wisconsin – investigating multiple sites with the National Map's “advanced viewer”

Lake Agassiz was an inland sea of freshwater, dwarfing the Great Lakes that drained catastrophically thru multiple routes back to the oceans. Mid-continent spillways contain meandering underfit rivers, but were once channels for huge volumes of melt

Historical reference for the evolution of the Missoula Floods that Harlen Bretz identified in the 1920’s by traversing the Channeled Scablands of eastern Washington, speculating that the floods came from accelerated Cordilleran ice sheet melting

Articles that purport to kill the whole Younger Dryas Impact Hypothesis / geomorphic imprints right into the surface of the Earth of gigantic megafloods – meltwater episodes of inconceivably humongous volumes of water discharging off the ice sheets

Evidence for nanodiamonds in Oklahoma Panhandle / chart of Volcanic Explosivity Index / ash from Mount St. Helens has been found and dated within the Scablands floods’ rhythmites, basis for theories of repeated Lake Missoula dam-break outburst floods

The most comprehensive paper detailing the findings of nanodiamonds at 24 sites in ten countries across three continents, and a 2008 contribution that sought to slam the YDIH as soon as it was presented, noting odd timing and fallacy-filled arguments

Behind the scenes: Break-time talk and the Brothers of the Serpent show the curious mountain of dark rocks in Cooktown, Queensland, Australia, called appropriately: Black Mountain

Scoured valleys in the Appalachians are filled with cobbles and boulders that tell a specific and catastrophic story. Giant boulder deposits, imbrication. Excellent gateway that dabbles into our forthcoming multi-episode journey into megafloods!

RC reviews the necessity to get these details and fingerprints covered thoroughly, as we are beginning to make the deliberate segue from YDB evidence into megafloods. He shares multiple accounts of meteors/fireballs reported in the early 20th century

Tunguska witnesses’ accounts and photos from Leonid Kulik’s team excursions into blast zone, as we ponder what forces could've inspired the frightful anecdotes and created the many odd features that remain – some of them reminiscent of Carolina Bays
