ORIGINAL: jeafl I am not familiar with any of the examples that you gave, but if the phenomenon of a glacier moving massive objects from one place to another has been observed within our lifetime, what reason is there to assume glaciers take thousands or millions of years to move boulders? The movement of a glacier is dependent on the slope it is on. If the slope is steep then the glacier moves quickly. A good example is the Grand Tetons where the jagged peaks were formed due to glaciers between the peaks. If the slope is not steep then the glaciers move slowly such as in the American NE and Minnesota (a land of a thousand glacier formed lakes). quote:
Isn’t the growth and recession of glaciers a product of weather and not necessarily a product of time? Couldn’t a decade of severely cold weather make a glacier do within the decade what it would otherwise do in a century with warmer weather? The first thing you need to do is make the glaciers. Most of the northern part of American was covered in glaciers that were several hundred to miles thick, much like the thickness of the ice in Antarctica. A flood does not cause this type of glaciation, and it takes quite a while to build up this much ice.
