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

Will send you my notes and maps for area between Manistee to Hart but you may need to mount them on cloth as the paper is rather rotten. At Ludington, try to find JA Mitchell, a surveyor who knows the country well; he helped me out considerably. Roads do not follow section lines there. In northern Mason Co. you may find north end of Lake Chicago beaches and learn their relations to Port Huron Moraine. Notes from Grant Township on weak moraines, wet tracts, abandoned roads that can only be travelled by horse or foot, pitted gravel plains. Mr. Mitchell gave me accurate levels for beach in Ludington: 636' = Calumet(?), and a higher beach 660' at Amber with Amber Station at 671'. Goldthwait could probably do this in a day. Try to trace beach from Victory Township NW to Hamlin Tp. Bass Lake is another good place for Goldthwait to level the beaches on the S and W sides of the lake, and also the till ridge that runs S to Pentwater. This ridge at 650' may have been covered by highest stage of Lake Chicago. Two miles N of Hart I hand-leveled from Pentwater River and found upper beach of Lake Chicago at 62' or 647' above tide. Beaches of Lake Chicago are only found in embayments because the border of Oceana CO. is so high; look for embayments for Goldthwait to level. Hope you have a fine time at the Taylor cottage .
