Internal Geometry and Evolution of Moulins
Journal of Glaciology, Vol. 34, No. 117 , 1988 INTERNAL GEOMETRY AND EVOLUTION OF MOULINS, STORGLACVlREN,~DEN By PER HOLMLUND (Department of Physical Geography, University of Stockholm, S-106 91 Stockholm, Sweden) ABSTRACT. The initial conditions needed for formation of moulins are crevasses and a supply of melt water. Water pouring into a crevasse may fill it until it overflows at the lowest point, which is normally near the margin. However, as the crevasse deepens, it intersects englacial channels through which the water can drain. These channels may be finger-tip tributaries in a dendritic system such as that described by Shreve (1972) and observed by Raymond and Harrison (1975). When the crevasse closes, heat in the melt water 'keeps the connection open and a moulin is formed. The englacial channel enlarges rapidly by melting, utilizing mechanical energy released by the descending water. Descents into moulins, and mapping of structures exposed at the surface after many years of melting, demonstrate that the drainage channels leading down from the bottoms of the moulins have inclinations of 0-45 0 from the vertical. These channels trend in the direction of the original crevasse but appear to be deeper than the expected depth of the crevasse. They have not, even at depths of 50--60 m, become normal to the equipotential planes described by Shreve. INTRODUCTION Fig . 1. Map showing the location of Storglaciiiren.

Lake Ontario a Voice!
Statue Stories Chicago: The Public Writing Competition Give Lake Ontario a voice! Behind the Art Institute of Chicago, is the Fountain of the Great Lakes. Within the famous fountain is the wistful figure of Lake Ontario. She sits apart from her sister lakes, gazing into the distance with arms outstretched. But what does she have to say for herself? Write a Monologue! Monologos means “speaking alone” in Greek, but we all know that people who speak without thinking about their listener can be very dull indeed. Your challenge is to find a ‘voice’ for your statue and to write an engaging monologue in 350 words. Get under your statue’s skin! Look closely and develop a sense of empathy with the sculpture and imagine how it would feel. How does Lake Ontario feel about her sister lakes? Invite your listener to feel with you: create shifts in tempo and emotion, use different tenses, figures of speech and anecdotes, sensory details and even sound effects. Finding your sculpture’s voice? Write in the first person and adopt the persona of your character: What kind of vocabulary will you use - your own or that of another era/dialect? Your words will be spoken so read them aloud: use their rhythm and your sentence structure to convey emotion and urgency. Read great monologues for inspiration, for example Hamlet’s Alas Poor Yorick, or watch film monologues, like Morgan Freeman’s in The Shawshank Redemption. How will you keep people listening? Structure your monologue! How will you introduce yourself? With a greeting, a warning, a question, an order, a riddle? Grab and hold your listener’s attention from your very first line. -

Indiana Glaciers.PM6
How the Ice Age Shaped Indiana Jerry Wilson Published by Wilstar Media, www.wilstar.com Indianapolis, Indiana 1 Previiously published as The Topography of Indiana: Ice Age Legacy, © 1988 by Jerry Wilson. Second Edition Copyright © 2008 by Jerry Wilson ALL RIGHTS RESERVED 2 For Aaron and Shana and In Memory of Donna 3 Introduction During the time that I have been a science teacher I have tried to enlist in my students the desire to understand and the ability to reason. Logical reasoning is the surest way to overcome the unknown. The best aid to reasoning effectively is having the knowledge and an understanding of the things that have previ- ously been determined or discovered by others. Having an understanding of the reasons things are the way they are and how they got that way can help an individual to utilize his or her resources more effectively. I want my students to realize that changes that have taken place on the earth in the past have had an effect on them. Why are some towns in Indiana subject to flooding, whereas others are not? Why are cemeteries built on old beach fronts in Northwest Indiana? Why would it be easier to dig a basement in Valparaiso than in Bloomington? These things are a direct result of the glaciers that advanced southward over Indiana during the last Ice Age. The history of the land upon which we live is fascinating. Why are there large granite boulders nested in some of the fields of northern Indiana since Indiana has no granite bedrock? They are known as glacial erratics, or dropstones, and were formed in Canada or the upper Midwest hundreds of millions of years ago. -

Kark's Canoeing and Kayaking Guide to 309 Wisconsin Streams
Kark's Canoeing and Kayaking Guide to 309 Wisconsin Streams By Richard Kark May 2015 Introduction A Badger Stream Love Affair My fascination with rivers started near my hometown of Osage, Iowa on the Cedar River. High school buddies and I fished the river and canoe-camped along its lovely limestone bluffs. In 1969 I graduated from St. Olaf College in Minnesota and soon paddled my first Wisconsin stream. With my college sweetheart I spent three days and two nights canoe- camping from Taylors Falls to Stillwater on the St. Croix River. “Sweet Caroline” by Neil Diamond blared from our transistor radio as we floated this lovely stream which was designated a National Wild and Scenic River in 1968. Little did I know I would eventually explore more than 300 other Wisconsin streams. In the late 1970s I was preoccupied by my medical studies in Milwaukee but did find the time to explore some rivers. I recall canoeing the Oconto, Chippewa, Kickapoo, “Illinois Fox,” and West Twin Rivers during those years. Several of us traveled to the Peshtigo River and rafted “Roaring Rapids” with a commercial company. At the time I could not imagine riding this torrent in a canoe. We also rafted Piers Gorge on the Menomonee River. Our guide failed to avoid Volkswagen Rock over Mishicot Falls. We flipped and I experienced the second worst “swim” of my life. Was I deterred from whitewater? Just the opposite, it seems. By the late 1970s I was a practicing physician, but I found time for Wisconsin rivers. In 1979 I signed up for the tandem whitewater clinic run by the River Touring Section of the Sierra Club’s John Muir Chapter.
