Estimates of glacial erosion rates using cosmogenic nuclides in bedrock are an order of magnitude lower than sediment-derived erosion rates, suggesting the higher rates are overestimated due to timescale biases or nonglacial sources of sediment. In PNAS: ow.ly/SQbR50ZxGwr

A 1959 peer review. It's of Fred Thwaites' manuscript, "Evidences of dissected erosion surfaces in the Driftless Area," submitted to GSA Bulletin. I wonder who anonymously said it was "a re-hash of older opinions without any new data". Published later in the Transactions of the Wisconsin Academy.
Typed text: "It is my belief that this paper should not be published in its present form. For the most part it is a re-hash of older opinions without any new data. As a matter of fact, there is no new interpretation either as the author comes to the same conclusion as Martin did long ago. There are many references to earlier opinions without stating specifically who expressed them. Some of these are clear cut cases of beating dead horses. Others are apparently the result of a grudge against the Geological Survey and perhaps still other sources that are less apparent. If this paper is ever to be published it must be carefully rewritten. I have made no effort to correct the many grammatical and typographical errors. So far as I can tell, there is nothing publishable in this report. However, some additional work might make it worthy of a note in the Bulletin."

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.
