Excerpt from Geography and Geology of Minnesota, Vol. 1The theme of this book is the Geography of Minne sota in its most essential and fundamental aspects. While the principles set forth are world-wide in their ap plication, the illustrations used to enforce them are drawn almost wholly from the features and phenomena of the state. Wherever state lines are ignored and the boundary is crossed it is to secure what seems neces sary to make clear the causes of conditions about us. For instance: almost the whole state presents manifold evidence of the work of glaciers, to show a glacier and its setting as a physical factor, appeal is made to the Yoho valley near the summit of the Albertan Rockies. Figure 29, Chapter VIII, is a picture of the interesting Yoho glacier. As the pupil looks at this picture and, in imagination, sees it expand into an ice stream hundreds of miles long and scarcely less in width, its moraines, in places, looming up hundreds of feet high and its wash filling prairies and plains scores of feet in depth, with identically the same materials as one finds every where throughout the state, there will become clear to the mind conditions well-nigh universal in Minnesota only a few thousand years ago.This book is not written in the style usual in text books of the schools.
