Grad student Tanner May has a new fun paper out in the Journal of Glaciology that is kind of magical. The magic trick that Tanner performs is that he manages to estimate thickness of glaciers using only surface elevations and nothing else.
This shouldn't work, but it does. Let me tell you why.

The bathymetry of eastern Lake Superior, the part that would be crossed by an ore carrier coming from the NW, trying to make Whitefish Bay in a storm, is fascinating. I have heard those N-S troughs explained as subglacially eroded tunnel channels, but there are probably other ideas out there.
