I returned on Tuesday from field work in MN, where the weather was better than any place here or west to NE. Alden was hindered by rain in IA. Sardeson worked with me the whole season; I turned over the most complicated parts of the Wisconsin drift to him where the movements from 3 spreading centers (Labrador, Patrician and Keewatin) overlapped each other. He cleared up the work nicely. He can differentiate certain rocks better than I can and he is a close observer. I feel confident his interpretations will stand, unlike Upham's as published in the Minnesota Survey. Mr. Alden worked the Iowan drift and has determined that there is a post-Kansan drift in NE IA east of the Des Moines Lobe. He has not determined its age or extent yet. Salisbury & I went to see what he found and we agreed with him. From Delaware to norrthern Johnson Counties, it underlies the deeply weathered surface of the Kansan drift, but does not cover it completely. It seems to have been a very thin and not continuous drift. We are inclined to think its age is nearer the Wisconsin than the Iowan, but it was decided to call it Iowan for the present. I inclose a clipping from the Nation in reference to our Monograph. I wonder if W.M. Davis wrote it. If you already have the clipping, please return it to me; otherwise keep it. Are you going to the GSA Meeting? I am planning to go, and stay a few days later to turn over my map of NE MN to the publisher in Washington. The southern half will make another sheet and complete the State Survey publication. I will also prepare another bulletin or professional paper on the Minnesota relations of the Keewatin, Patrician, and Labrador ice movements. I think this will be published by USGS. Another similar paper will cover the Northern Peninsula of MI, north WI, and NE MN, and will deal with the Labradoran ice sheet drift around the Superior Basin and the lake history as the ice melted. In MN, I found evidence of a pre-Agassiz Lake at the SE border of the Lake Agassiz district in Koochiching and St. Louis counties N of the Mesabi range. Its outlet ran across the Mesabi Range along the course of the Embarass River. Its shoreline is about 100' above any of the Agassiz beaches and the outlet is nearly 1400' at its head. The head is where the Pike River turns N to Vermillion Lake. A marshy channel runs from this bend of the Pike River S to the Embarass River and then to the St. Louis River crossing the Mesabi Range between Biwabik and Aurora. This may be my paper at GSA. It seems a long time since I heard from you. I have thought of you often in the field season and wondered whether you were out in the wet or snugly seated at your desk, or eating cracker jack with Mrs. Taylor. We shall be glad to hear from you again. Mrs. Leverett's mother came with me and will stay with us this winter, as well as a cousin of mine, Mrs. Dewing, a daughter of Mr. Brackett the pomologist. Mr. Brackett died in August and this daughter had been staying with him. She will be with us until she can arrange for a place of her own.
