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 am sending map of the Ottawa OH quadrangle on which I have indicated shorelines, but I erred in calling one beach Whittlesey in Palmer Township. You can refer to Monograph 41, p. 749-50, to find statements on Whittlesey that you will need to correct. 2nd Maumee averages 770' east of Otttawa. Inclosing elevation notes on beaches on Ohio topo sheets for you to use. It appears that highest Maumee may not appear on inner slope of Defiance Moraine, and there are other discrepancies about 2nd and 3rd Maumee beaches, and there is a gradual rise in shorelines from Cleveland east, so my hingeline can not be so far east. There are 2 beaches east of Cleveland below the Belmore -- is the higher the Arkona or does the Upper Warren split at Cleveland/ The lower of these 2 remains steady at 680' all the way to Pennsylvania. We need to clear this up -- perhaps a few days spent east of Cleveland witht eh topo maps? I am surprised to find the 2nd and 3rd Maumee so low on the Ottawa & Deshler maps, for the Belmore is not any lower than usual but all the beaches are slightly lower than normal in the Oberlin sheet.
