Scope and Contents

From the Series:

The correspondence series includes approximately 1100 letters written between 1892-1939. The majority of the collection are letters between Frank Leverett and Frank Bursley Taylor; they discuss their field work, Monograph 53, other publications and various related problems. There is also other correspondence with other geologists, including T.C. Chamberlin, Grove K. Gilbert, J.W. Goldthwait, H.L. Fairchild, et alia. There is extensive correspondence with the U.S. Geological Survey, the Geological Survey of Canada, and the Michigan Geological Survey. The primary subject of this series is the surficial glacial geology of the midwestern U.S. and Canada. Leverett & Taylor's work was essential for understanding how the Great Lakes were formed as the Pleistocene glaciers advanced and retreated from the midwestern states. The letters describe the 30 year process of gathering data, mapping the data and constructing the picture of glacial processes during the last Ice Age.

Additional Description

General

I gave your chapter on the possible causes of deformation of shore lines a careful read, and think it is an admirable discussion on the subject. I was very interested to see you use my studies in northern MN, but would suggest one slight change in that section to the effect that the area just east of the limits of the Keewatin lobe was not covered by the Labrador lobe in earlier Wisconsin time. Also I do not consider the clays mentioned on p. 28-31 to be interglacial, and they may have been laid down in the finger-lakes before the next ice advance. It might be advisable to omit this section, or perhaps retain the part dealing with Toronto clay beds and make a reference to the clays in northern Lower Penisula. I think we should make a clean copy to send to Washington, and I can have this done here in Ann Arbor, but we should defer final copying until Chamberlin has made any revisions. On the map of Algonquin isobases I can insert an isobase at 935-940' that will parallel the 1015 line to the N and the 857 line to the S. I would like to clarify the legend for fig.12. The glacial map of Michigan has been transferred to the new base, but I find the Warren and Algonquin beaches were so questionable in the Saginawa basin that I think we should put a note in the legend that the mapping here is incomplete. We should probably hold the MS and the maps until after the Academy of Science meeting so we can take a final look at them together. The Academy meeting will be very interesting so you and Mrs. Taylor must be sure to attend.
