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

Lane & I spent 2 days E of Elkton and found highest beach is continuous on both sides of Thumb at altitudes 744 to 775'. Davis may be mistaken about highest Warren level near Gagetown, but Lane's Grassmere at 700 lies west of Gagetown, but not at border of moraine. Present understanding of beaches is Arkona at highest, with upper Forest a few ft. lower, then the lower Forest (Lane's Grassmere). Arkona rises 700' at Ann Arbor to 775' on storm beach in Huron Co., Upper Forest rises from 680-685' at Detroit to about 755-760' at Thumb, and Lower Forest rises 654-665' in Wayne Co. to above 710' in Huron Co. (if Grassmere is same). Channels at Ubly, Tyre and Cumber. Gordon's moraine maps in NW Sanilac Co. is not complete; do you have enough data to work around his deficiencies? If not would you put your data on moraines and shore lines onto the Sanilac Co. map from my state atlas and send as soon as possible? Will write you more fully later and send map of Huron Co.? PLUS 3 pages on notes on Huron Co. from Nov. 1903.
