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

Col. Millis, now in Chicago, sent me a MS on the "Glacial Period and the Drayson Hypothesis" for criticism, and I presume he sent it to you as well. I inclose a copy of my letter to him. If you have read the Drayson Hypothesis you may judge as to whether it is sound on the matter of the 2nd rotation of the earth being only 32000 years and its effect on the climate zones. If you have read the Hypothesis I should be glad to hear how it impressed you. I just had my leg taken out of suspension after 9 weeks and I hope to leave the hospital in a few days. The surgeon thinks the leg is in pretty good shape. I found Cushing's letter about the ice deepening the Cuyahoga River; the bed rock is the weakest shale and could be easily eroded. Ice ice here was 600' thicker than over the adjacent upland. Cushing is reminded of the narrow linear lakes in the Trent Valley where every valley was deepened by hthe ice into a linear lake. I failed to ask if you will be spending part of the remainder of the summer at Mackinac Island.
