This paper is a description of the chief geologic features that may be seen along Highway No. 1 of Minnesota. This highway begins at the Iowa state line south of Albert Lea, and passes northward through the Twin Cities to Duluth and thence extends along the north shore of Lake Superior to the Pigeon River near Port Arthur, Ontario. The report includes thirteen maps which show the locations of roads, towns, and villages, and most of the rocks and land forms that are described in the text. Essentially all places mentioned in the text ale located on one of the maps. The work was in charge of Dr. G. M. Schwartz who traversed the entire route and prepared the text. Numerous earlier re- ports by the Geological Survey of Minnesota and the United States Geological Survey were drawn upon for data and these are appropriately acknowledged in the text. A section on trees and plants is supplied by Dr. C. O. Rosendahl and Dr. F. K. Butters, of the University. of Minnesota, and one on fish and game by Mr. Thaddeus Surber, The paper is intended for the use of the traveler and the general public and as far as practicable highly technical terms are avoided.
