Get reoriented with Finger Lakes, NY, region’s topography and erosion features / geomorphology that must have resulted from regional floods / more landforms that were from catastrophic subglacial discharges / varied flow-forms all around Lake Ontario

We get back into the formation of drumlins and the problem of scale, while revealing massive swarms in and around Lake Ontario, which includes a deep basin that seems an emanation point for the radial Finger Lakes.

Effects of the blast wave from the central Arizona impact 50,000 years ago / detonations of nuclear weapons during the 1950’s / estimates for a similar event every 1600 years are pondered – considered to be even shorter now?

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
