Episode #025: The Life Cycle of Comets

Randall’s back-drop sparks discussion of meteor showers and the progression of a disintegrating comet to provide the material for multiple impacts. We have learned critical lessons from Shoemaker-Levy 9, the KT boundary impact event, Tunguska, and nuclear detonations. He gets back into the work of Ted Bunch et al that compares impact markers from these events with the evidence for the YDIH. Lack of a crater is problematic to critics, but an oblique/tangential grazing of a passing object above the ice sheet is the scenario RC prefers, and includes drumlins as one of the potential effects that we now see in the landscapes.
