  • Since the west coast of the US rests along the great Pacific rim fault line, isostatic depression may have caused a thinning of the Earth's mantle (liquification) allowing more isothermal activity to migrate upwards, contributing to subglacial melting on a large scale. Is there a way to estimate the temperature of this subglacial water by analyzing such things as biological elements (dormant molds, algae, etc.) within drumlins? It seems that heat, possibly from tectonic activity, would have played a major role in this event.

  • If there was a different climate and landscapes, there would be millions of tons of debris along with water to create even more friction..
