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 have been working around Marquette for the last week with your paper on shorelines of southern Lake Superior in hand as I went. I did not find the beach you mentioned on the road to Negaunee, although the broken ridges there may be glacial in origin. Large flat area near Eagle Mills has a definite gravel bank on SW border but this is a glacial drainage line to Escanaba River. Similarly, the line of drainage from Pelissius Lake, and a channel that sits into a moraine at 1130' between the Carp and Escanaba rivers. Highest shore at Marquette is 860' and is very weak, with a stronger one at 830'. A strong shore line crosses the Munising RR at 793', and fine shoreline near the Marquette Electric Light Station at 710'. The Nipissing is at 630'. I think the 793' line is the Algonquin, and the higher ones are the products of local lakes. Or the 710' is the Nipissing, the 630' is Algoma, and the 793' is the Battlefield and the next higher is the Algonquin. The shores are easier to work out here than further east.
