  • Vegetation and Fire at the Last Glacial Maximum in Tropical South America
    Past Climate Variability in South America and Surrounding Regions Developments in Paleoenvironmental Research VOLUME 14 Aims and Scope: Paleoenvironmental research continues to enjoy tremendous interest and progress in the scientific community. The overall aims and scope of the Developments in Paleoenvironmental Research book series is to capture this excitement and doc- ument these developments. Volumes related to any aspect of paleoenvironmental research, encompassing any time period, are within the scope of the series. For example, relevant topics include studies focused on terrestrial, peatland, lacustrine, riverine, estuarine, and marine systems, ice cores, cave deposits, palynology, iso- topes, geochemistry, sedimentology, paleontology, etc. Methodological and taxo- nomic volumes relevant to paleoenvironmental research are also encouraged. The series will include edited volumes on a particular subject, geographic region, or time period, conference and workshop proceedings, as well as monographs. Prospective authors and/or editors should consult the series editor for more details. The series editor also welcomes any comments or suggestions for future volumes.

  • 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.

  • Sculpted by Floods Learning Resource Guide Overview
    Sculpted by Floods Learning Resource Guide Overview: KSPS’s Sculpted by Floods tells the story of the ice age floods in the Pacific Northwest. It is a story of the earth's power, scientific discovery and human nature - one touted by enthusiasts as the greatest story left untold. During the last ice age, floods flowing with ten times the volume of all the world's current rivers combined inundated the Northwest. What they left behind was a unique landscape that citizens of the Pacific Northwest call home. Subjects: Earth Science, Geology, History, Pacific Northwest History Grade Levels: 6-8 Materials: Lesson handouts, laptops/computers Learning Guide Objectives: Define the following vocabulary terms and use them orally and in writing: glacier, flood, cataracts, landform, canyon, dam. Analyze how floods can create landforms and shape a region’s landscape, using the Missoula Floods as a case study. Next Generation Science Standards MS-ESS2-2.

HUNTTING, Supervisor Bulletin No. 45 WASHINGTON'S CHANNELED SCABLAND By .T HARLEN BRETZ l•or sate by Department or Conservation, Olympia, Washington. Price, 50 cents. FOREWORD Most travelers who have driven through eastern Washington have seen a geologic and scenic feature that is unique-nothing like it is to be found anywhere else in the world. This is the Channeled Scab­ land, a gigantic series of deeply cut channels in the erosion-resistant Columbia River basalt, the rock that covers most of the east-central and southeastern part of the state. Grand Coulee, with its spectac­ ular Dry Falls, is one of the most widely known features of this ex­ tensive set of dry channels. Many thousands of travelers must have wondered how this Chan­ neled Scabland came into being, and many geologists also have speculated as to its origin. Several geologists have published papers outlining their theories of the scabland's origin, but the geologist who has made the most thorough study of the problem and has ex­ amined the whole area and all the evidence having a bearing on the problem is Dr. J Harlen Bretz.

I would first like to thank Bill Bush forsuggesting the idea of doing graduate work in geology at WMU. Two of my cohorts in the department, Andrew Kozlowski and Brian Bird, deserve special recognition for endless hours of ruminating with me about many things, in particular about the last 20,000 years in southwest Michigan. I wish also to thank Andrew forstepping out of his pessimistic outlook to offerme continual encouragement to pursue science and academia. Brian was always willing to spend time making figures and answering my constant questions about GIS, Canvas, and a host of other programs.
