These currents, unlike Shaw's subglacial floods, were caused by tectonic adjustments associated with the recession of the floodwaters from the continents. My theory is that bedrock drumlins were formed when the rock was unconsolidated. The environment in which drumlins are formed appeared to be one of large landmasses which have been swept by catastrophic floods, a factor which supports Cox's flooding hypothesis. Huge fields of drumlins occur with a parallel orientation so perfect that only a massive water flow could have produced them. It is suggested that where floodwaters surged quickly over level plains of unconsolidated deposits, a streamlined bed would develop.
Rapid currents possess momentum, and momentum of currents are responsible for patterns of drumlins .
The form of drumlins is one which minimizes turbulence. It seems unrealistic that something as slow moving as a glacier would create features to minimize turbulence. In their effort to explain drumlins in terms of the glacial theory, investigators have confused effects which are actually indicative of rapid fluid flow with effects that moving ice may produce due to its rigidity. Cox's flood can not be entirely attributed to glacial melting. There are many indications that vertical fluctuations of the earth's crust were a large aspect of the flood.
