Resources provided valuable limnologic data, in Swain, Professor, Department of Geology and particular the reports of John B. Moyle and John Geophysics, University of Minnesota, was first Dobie. The late Samuel Eddy provided much submitted to the Minnesota Geological Survey in helpful information. Kendell A. Dickinson assisted early 1969. After several technical reviews, P.K. with much of the field work. M. Alan Rogers, Sims, Director of the Survey at the time, approved Harvey Meyer, Peter Fleischer, Mikola the manuscript for publication on May 31, 1969. Malinowsky, Dennis Deischl, Gunta V. Pakalns, Sims intended to publish the report as part of the Inara Porietis, David Peterson, Judy M. Bratt, Geological Survey's Special Publication Series. Patricia Bloomgren, and Shirley Kraemer, at the For reasons long forgotten, the report languished in University of Minnesota, assisted with the field and the files for several years. After a severe financial laboratory work. The Graduate School, the cutback in 1972, P. K. Sims resigned as Director; Minnesota Geological Survey, and the he was replaced by Matt S. Walton.
