Drumlin Formation Not Necessarily Evidence Of Catastrophic Event

Drumlin Formation Not Necessarily Evidence Of Catastrophic Event

People have selectively used the ideas of Dr. John Shaw to claim that they are undisputed indicators of catastrophic subglacial floods associated with extraterrestrial impacts. However, in their arguments, they completely either ignore over overlook any other research that strongly indicate that there is a lack of
any connection between catastrophic subglacial floods and drumlin formation. Some of this recent research is:
Observations from the surge-type glacier Múlajökull in Iceland underpin new modeling results that suggest the glacier's drumlins grow during quiet intervals of normal flow between glacial surges.
