But the storm also had effects clear up into Lake Michigan:
While assessing Ike's impact on the lake, Whitman noted that "The velocity and height of a tributary emptying into Lake Michigan at Portage, Indiana went off the chart. We measured a tremendous amount of sediment accumulation near Ogden Dunes."A minor footnote in the record of Ike's passing, to be sure; but a plain reminder of the lasting and unusual power of a hurricane.
