Introduction to Geological Process in Illinois Glacial
INTRODUCTION TO GEOLOGICAL PROCESS IN ILLINOIS GLACIAL PROCESSES AND LANDSCAPES GLACIERS A glacier is a flowing mass of ice. This simple definition covers many possibilities. Glaciers are large, but they can range in size from continent covering (like that occupying Antarctica) to barely covering the head of a mountain valley (like those found in the Grand Tetons and Glacier National Park). No glaciers are found in Illinois; however, they had a profound effect shaping our landscape. More on glaciers: http://www.physicalgeography.net/fundamentals/10ad.html Formation and Movement of Glacial Ice When placed under the appropriate conditions of pressure and temperature, ice will flow. In a glacier, this occurs when the ice is at least 20-50 meters (60 to 150 feet) thick. The buildup results from the accumulation of snow over the course of many years and requires that at least some of each winter’s snowfall does not melt over the following summer. The portion of the glacier where there is a net accumulation of ice and snow from year to year is called the zone of accumulation. The normal rate of glacial movement is a few feet per day, although some glaciers can surge at tens of feet per day. The ice moves by flowing and basal slip. Flow occurs through “plastic deformation” in which the solid ice deforms without melting or breaking. Plastic deformation is much like the slow flow of Silly Putty and can only occur when the ice is under pressure from above. The accumulation of meltwater underneath the glacier can act as a lubricant which allows the ice to slide on its base. -

The Larval Stages of Trilobites

It is now generally known that the youngest stages of trilobites found as fossils are minute ovate or discoid bodies, not more than one millimetre in length, in which the head por tion greatly predominates. Altogether they present very little likeness to the adult form, to which, however, they are trace able through a longer or shorter series of modifications. Since Barrande2 first demonstrated the metamorphoses of trilobites, in 1849, similar observations have been made upon a number of different genera by Ford,22 Walcott,34':*>':t6 Mat thew,28- 27' 28 Salter,32 Callaway,11' and the writer.4.5-7 The general facts in the ontogeny have thus become well estab lished and the main features of the larval form are fairly well understood. Before the recognition of the progressive transformation undergone by trilobites in their development, it was the cus tom to apply a name to each variation in the number of tho racic segments and in other features of the test. -
The Physical Geography of the Illinois River Valley Near Peoria
The Physical Geography of the Illinois River Valley Near Peoria An Updated Self-Conducted Field Trip using EcoCaches and GPS Technology Donald E. Bevenour East Peoria Community High School Illinois State University Copyright, 1991 Updated by: Kevin M. Emmons Morton High School Bradley University 2007 Additional Support: Martin Hobbs East Peoria Community High School Abstract THE PHYSICAL GEOGRAPHY OF THE ILLINOIS RIVER VALLEY NEAR PEORIA: AN UPDATED SELF CONDUCTED FIELD TRIP USING ECOCACHES AND GPS TECHNOLOGY This field trip has been written so that anyone can enjoy the trip without the guidance of a professional. The trip could be taken by student groups, families, or an individual; at least two people, a driver and a reader/navigator, are the recommended minimum number of persons for maximum effectiveness and safety. Subjects of discussion include the Illinois River, the Bloomington, Shelbyville, and LeRoy Moraines, various aspects of the glacial history of the area, stream processes, floodplains, natural vegetation, and human adaptations to the physical environment such as agriculture, industry, transportation, and growth of cities. Activities include riding to the top of a lookout tower, judging distance to several landmark objects, and scenic views of the physical and cultural environment. All along the trip, GPS coordinates are supplied to aid you in your navigation. Information on EcoCaches is available at http://www.ilega.org/ Why take a self-guided field trip? A self-guided field trip is an excellent way to learn more about the area in which one lives. Newcomers or visitors to an area should find it a most enlightening manner in which to personalize the new territory. -

Previous Work The Brassfield Formation has been studied at least since before 1838 by Owen in Indiana. It was originally correlated with the Clinton of New York by Orton {1871), based on strat igraphy and lithology rather than on faunal evidence. Due to differences in fauna, Foerst (1896) proposed a land barrier between the two and proposed the name Montgomery limestone for the typical development in Montgomery County, Ohio. The name lapsed, and in 1906 he renamed the Clinton beds in Ken tucky the Brassfield, and three years later he did the same for the Clinton age beds in Ohio.
