RC and crew again attempt to grok the widespread shifts that would have filled the many proglacial lakes and released the catastrophic drainings across the landscapes. What was the chronology of these interrelated events? Ice dam and Missoula Floods

More drumlins and their formation at the base of the continental ice sheets that covered Canada. The catastrophic release of Glacial Lake Agassiz into Minnesota and the relict oversize spillways containing underfit rivers.

Jerome Lesemann PhD, is a drumlin expert and student/colleague of John Shaw – pioneer of the Meltwater Hypothesis. The enigmatic geomorphological features are present far and wide across North America, beneath the former continental ice sheets

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Historical reference for the evolution of the Missoula Floods that Harlen Bretz identified in the 1920’s by traversing the Channeled Scablands of eastern Washington, speculating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

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!
