NE Arizona and SE Utah: RC shares his images and scrolls around maps. We visited Sedona, Meteor Crater, Rock Art Ranch, Monument Valley, the Great Goosenecks, Mexican Hat, Valley of the Gods, Montezuma’s “Castle”, Montezuma’s Well, and Tuzigoot ruins

Sites we’ll be visiting on the “Southwest Experience” tour / reminiscing about prior trips and a memorable retreat in Colorado’s Sangre de Cristo Mountains / reminded of links between micro/macro evidence that can help identify ice sheet impact sites

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Historical reference for the evolution of the Missoula Floods that Harlen Bretz identified in the 1920’s by traversing the Channeled Scablands of eastern Washington, speculating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