...meanders and oxbow lakes are less common in New England, since many of the rivers and river beds moved during last ice age, so many of the rivers are newer-- speaking on a geological time scale. ~ of troy

Maybe so, of troy, but it shouldn't be so. During ice ages sea levels are lowered some 400 feet. This increases the gradient and rivers would tend to entrench by straight-line downcutting and discharge more directly into a lower, lesser sea.
