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. -

Thus, some 14,000 years ago as the last glacier receded millions of years to form. We can see evidence of tropical sea into the Lake Erie basin, the first Native Americans arrived and reefs on the Lake Erie Islands and deep ocean sediments here in began to utilize the natural resources that these natural processes the cliffs of the Black River. Ohio was just south of the equator had produced. at that time, some 350 million years ago, and over the millennia The natural history of Sheffield encompasses all those natural has migrated northward to its present position. Mountain features and processes of the environment that greeted the Native building to the east eventually raised the sea floor from under Americans, and later the pioneers, when they first arrived in the waves and erosion by streams, and later glacial ice, began Sheffield. To be sure, the landscape was a magnificent wilderness to sculpture the land. At the same time plants and animals were to the settlers, but it needed to be “tamed” in order to support evolving and began to populate the new land once the ice was the newcomers. Ice formation on the shale bluff of the Black River north of Garfield Bridge (2005). 1 BICENTENNIAL HISTORY OF SHEFFIELD TOPOGRAPHY Regional Physiography The topography of an area is the configuration of the land Physiography refers to the physical features or landforms of surface, including its relief [vertical differences in elevation of a region. -

The Evolution of Crayfishes of the Genus Orconectes Section Limosus (Crustacea: Decopoda)
THE OHIO JOURNAL OF SCIENCE Vol. 62 MARCH, 1962 No. 2 THE EVOLUTION OF CRAYFISHES OF THE GENUS ORCONECTES SECTION LIMOSUS (CRUSTACEA: DECOPODA) RENDELL RHOADES Department of Zoology and Entomology, The Ohio State University, Columbus 10 The earliest described crayfish species now included in the Section limosus of the Genus Orconectes was described by Samuel Constantine Rafinesque (1817: 42). He reported the species, which he named Astacus limosus, "in the muddy banks of the Delaware, near Philadelphia." How ironical it now seems, that when Rafinesque located at Transylvania three years later and traveled to Henderson, Kentucky, to visit a fellow naturalist, John J. Audubon, he could have collected from the streams of western Kentucky a crayfish that he might have identified as the species he had described from the Delaware. We now know that these streams of the knobstone and pennyroyal uplands are the home of parent stock of this group. Moreover, this parental population on the Cumberland Plateau is now separated from Rafinesque's Orconectes limosus of the Atlantic drainage by more than 500 miles of mountainous terrain. Even Rafinesque, with his flair for accuracy and vivid imagination, would have been taxed to explain this wide separation had he known it. A decade after the death of Rafinesque, Dr. W. T. Craige received a blind crayfish from Mammoth Cave. An announcement of the new crayfish, identi- fied as "Astacus bartonii (?)" appeared in the Proceedings of the Academy of Natural Science of Philadelphia (1842: 174-175). Within two years the impact of Dr. Craige's announcement was evidenced by numerous popular articles both here and abroad. -

Petition to List US Populations of Lake Sturgeon (Acipenser Fulvescens)
Petition to List U.S. Populations of Lake Sturgeon (Acipenser fulvescens) as Endangered or Threatened under the Endangered Species Act May 14, 2018 NOTICE OF PETITION Submitted to U.S. Fish and Wildlife Service on May 14, 2018: Gary Frazer, USFWS Assistant Director, [email protected] Charles Traxler, Assistant Regional Director, Region 3, [email protected] Georgia Parham, Endangered Species, Region 3, [email protected] Mike Oetker, Deputy Regional Director, Region 4, [email protected] Allan Brown, Assistant Regional Director, Region 4, [email protected] Wendi Weber, Regional Director, Region 5, [email protected] Deborah Rocque, Deputy Regional Director, Region 5, [email protected] Noreen Walsh, Regional Director, Region 6, [email protected] Matt Hogan, Deputy Regional Director, Region 6, [email protected] Petitioner Center for Biological Diversity formally requests that the U.S. Fish and Wildlife Service (“USFWS”) list the lake sturgeon (Acipenser fulvescens) in the United States as a threatened species under the federal Endangered Species Act (“ESA”), 16 U.S.C. §§1531-1544. Alternatively, the Center requests that the USFWS define and list distinct population segments of lake sturgeon in the U.S. as threatened or endangered. Lake sturgeon populations in Minnesota, Lake Superior, Missouri River, Ohio River, Arkansas-White River and lower Mississippi River may warrant endangered status. Lake sturgeon populations in Lake Michigan and the upper Mississippi River basin may warrant threatened status. Lake sturgeon in the central and eastern Great Lakes (Lake Huron, Lake Erie, Lake Ontario and the St. Lawrence River basin) seem to be part of a larger population that is more widespread. -

Weekly Update #7 – February 21, 2020
Water Level & Flow Update for the Lower Nelson River Weekly Update # 7 February 21, 2020 Lower Nelson River (Split Lake to Hudson Bay) Water up and impoundment has not started at Keeyask (planned to begin in February). Flows on the Nelson River are high as heavy Fall rainfall in the southern parts of the watershed flows north on its way to Hudson Bay - this will continue all winter. Hydro system flows to Split Lake and the Lower Nelson River come from 2 sources – Lake Winnipeg (LW) outflows through Kelsey generating station (at 3115 cms or 110,000 cfs) and Churchill River Diversion (CRD), through Notigi control structure (960 cms or 33,900 cfs)-see map. These combined flows (of 4,075 cms or 143,900 cfs) have been relatively constant since early December. The Nelson’s flow downstream of Keeyask is 4,480 cms ( or 158,200 cfs) (measured at As of February 19, Lower Nelson River lake and Limestone GS). forebay levels are: • Split Lake 168.35 m (or 552.3 ft) Nelson River flow depends on Lake Winnipeg Water level: • Clark Lake 167.94 m (or 551.0 ft ) Lake Winnipeg outflows are largely controlled by the • Gull Lake 156.17 m (or 512.4 ft ) Jenpeg Generating Station (upstream of Kelsey Jenpeg• Stephens Lake 139.76 m (or 458.5 ft) Generating Station). These flows are maximized every • Long Spruce forebay 110.90 m (or 361.2 ft ) winter to allow as much water as possible to flow out of • Limestone forebay 85.07 m (or 279.1 ft) Lake Winnipeg to fuel generating stations on the Nelson River to meet heating demands by Manitobans.
