The Lake Michigan Natural Division Characteristics
The Lake Michigan Natural Division Characteristics Lake Michigan is a dynamic deepwater oligotrophic ecosystem that supports a diverse mix of native and non-native species. Although the watershed, wetlands, and tributaries that drain into the open waters are comprised of a wide variety of habitat types critical to supporting its diverse biological community this section will focus on the open water component of this system. Watershed, wetland, and tributaries issues will be addressed in the Northeastern Morainal Natural Division section. Species diversity, as well as their abundance and distribution, are influenced by a combination of biotic and abiotic factors that define a variety of open water habitat types. Key abiotic factors are depth, temperature, currents, and substrate. Biotic activities, such as increased water clarity associated with zebra mussel filtering activity, also are critical components. Nearshore areas support a diverse fish fauna in which yellow perch, rockbass and smallmouth bass are the more commonly found species in Illinois waters. Largemouth bass, rockbass, and yellow perch are commonly found within boat harbors. A predator-prey complex consisting of five salmonid species and primarily alewives populate the pelagic zone while bloater chubs, sculpin species, and burbot populate the deepwater benthic zone. Challenges Invasive species, substrate loss, and changes in current flow patterns are factors that affect open water habitat. Construction of revetments, groins, and landfills has significantly altered the Illinois shoreline resulting in an immeasurable loss of spawning and nursery habitat. Sea lampreys and alewives were significant factors leading to the demise of lake trout and other native species by the early 1960s. -
AN OVERVIEW of the GEOLOGY of the GREAT LAKES BASIN by Theodore J
AN OVERVIEW OF THE GEOLOGY OF THE GREAT LAKES BASIN by Theodore J. Bornhorst 2016 This document may be cited as: Bornhorst, T. J., 2016, An overview of the geology of the Great Lakes basin: A. E. Seaman Mineral Museum, Web Publication 1, 8p. This is version 1 of A. E. Seaman Mineral Museum Web Publication 1 which was only internally reviewed for technical accuracy. The Great Lakes Basin The Great Lakes basin, as defined by watersheds that drain into the Great Lakes (Figure 1), includes about 85 % of North America’s and 20 % of the world’s surface fresh water, a total of about 5,500 cubic miles (23,000 cubic km) of water (1). The basin covers about 94,000 square miles (240,000 square km) including about 10 % of the U.S. population and 30 % of the Canadian population (1). Lake Michigan is the only Great Lake entirely within the United States. The State of Michigan lies at the heart of the Great Lakes basin. Together the Great Lakes are the single largest surface fresh water body on Earth and have an important physical and cultural role in North America. Figure 1: The Great Lakes states and Canadian Provinces and the Great Lakes watershed (brown) (after 1). 1 Precambrian Bedrock Geology The bedrock geology of the Great Lakes basin can be subdivided into rocks of Precambrian and Phanerozoic (Figure 2). The Precambrian of the Great Lakes basin is the result of three major episodes with each followed by a long period of erosion (2, 3).

Line 5 Straits of Mackinac Summary When Michigan Was Granted
Line 5 Straits of Mackinac Summary When Michigan was granted statehood on January 26, 1837, Michigan also acquired ownership of the Great Lakes' bottomlands under the equal footing doctrine.1 However before Michigan could become a state, the United States first had to acquire title from us (Ottawa and Chippewa bands) because Anglo-American law acknowledged that we owned legal title as the aboriginal occupants of the territory we occupied. But when we agreed to cede legal title to the United States in the March 28, 1836 Treaty of Washington ("1836 Treaty", 7 Stat. 491), we reserved fishing, hunting and gathering rights. Therefore, Michigan's ownership of both the lands and Great Lakes waters within the cession area of the 1836 Treaty was burdened with preexisting trust obligations with respect to our treaty-reserved resources. First, the public trust doctrine imposes a duty (trust responsibility) upon Michigan to protect the public trust in the resources dependent upon the quality of the Great Lakes water.2 In addition, Art. IV, § 52 of Michigan's Constitution says "conservation…of the natural resources of the state are hereby declared to be of paramount public concern…" and then mandates the legislature to "provide for the protection of the air, water and other natural resources from 3 pollution, impairment and destruction." 1 The State of Michigan acquired title to these bottomlands in its sovereign capacity upon admission to the Union and holds them in trust for the benefit of the people of Michigan.

Wisconsin's Wildlife Action Plan (2005-2015)
Wisconsin’s Wildlife Action Plan (2005-2015) IMPLEMENTATION: Priority Conservation Actions & Conservation Opportunity Areas Prepared by: Wisconsin Department of Natural Resources with Assistance from Conservation Partners, June 30th, 2008 06/19/2008 page 2 of 93 Wisconsin’s Wildlife Action Plan (2005-2015) IMPLEMENTATION: Priority Conservation Actions & Conservation Opportunity Areas Acknowledgments Wisconsin’s Wildlife Action Plan is a roadmap of conservation actions needed to ensure our wildlife and natural communities will be with us in the future. The original plan provides an immense volume of data useful to help guide conservation decisions. All of the individuals acknowledged for their work compiling the plan have a continuous appreciation from the state of Wisconsin for their commitment to SGCN. Implementing the conservation actions is a priority for the state of Wisconsin. To put forward a strategy for implementation, there was a need to develop a process for priority decision-making, narrowing the list of actions to a more manageable number, and identifying opportunity areas to best apply conservation actions. A subset of the Department’s ecologists and conservation scientists were assigned the task of developing the implementation strategy. Their dedicated commitment and tireless efforts for wildlife species and natural community conservation led this document.

FINAL GEOLOGIC REPORT Emerged
although the conditions of extreme chaos anticipated were not encountered. Geological exploration has established the solidarity of bedrock underlying the Straits of Mackinac and its adequacy to support the comparatively modest loads that will be imposed by the structure. D. B. STEINMAN, CONSULTING ENGINEER MACKINAC BRIDGE Some 300-400 million years ago in early to mid- Devonian time, the land mass in the area of the Straits FINAL GEOLOGIC REPORT emerged. This pseudo-uplift, due to the retreat of the Devonian sea, quickened ground water movement and Jack C. Rosenau thereby, leaching of the salt beds of the Salina Resident Geologist Formation of the Silurian Period. As a result of the April 20, 1956 leaching, two important geological formations came into being: (1) the brine water worked its way into the Michigan Basin and deposited the upper salt beds of the Introduction Detroit River Formation, and (2) the solution of large quantities of rock salt left great voids or cavernous areas The Straits of Mackinac is a 70-mile connecting link with an overlying rock mass of shales, limestones, between Lakes Michigan and Huron; its width at the site dolomites, cherts, sandy shales and gypsum or of the Mackinac Bridge is 4 miles and its depth is known anhydrite. These deposits are the Salina (Pointe Aux to be at least 290 feet below lake level (578.5’ USLS, Chenes) and Bass Island (St. Ignace) Formations of the MLWD).

Geology of Michigan and the Great Lakes
35133_Geo_Michigan_Cover.qxd 11/13/07 10:26 AM Page 1 “The Geology of Michigan and the Great Lakes” is written to augment any introductory earth science, environmental geology, geologic, or geographic course offering, and is designed to introduce students in Michigan and the Great Lakes to important regional geologic concepts and events. Although Michigan’s geologic past spans the Precambrian through the Holocene, much of the rock record, Pennsylvanian through Pliocene, is miss- ing. Glacial events during the Pleistocene removed these rocks. However, these same glacial events left behind a rich legacy of surficial deposits, various landscape features, lakes, and rivers. Michigan is one of the most scenic states in the nation, providing numerous recre- ational opportunities to inhabitants and visitors alike. Geology of the region has also played an important, and often controlling, role in the pattern of settlement and ongoing economic development of the state. Vital resources such as iron ore, copper, gypsum, salt, oil, and gas have greatly contributed to Michigan’s growth and industrial might. Ample supplies of high-quality water support a vibrant population and strong industrial base throughout the Great Lakes region. These water supplies are now becoming increasingly important in light of modern economic growth and population demands. This text introduces the student to the geology of Michigan and the Great Lakes region. It begins with the Precambrian basement terrains as they relate to plate tectonic events. It describes Paleozoic clastic and carbonate rocks, restricted basin salts, and Niagaran pinnacle reefs. Quaternary glacial events and the development of today’s modern landscapes are also discussed. -
Wisconsin's Door Peninsula and Its Geomorphology
WISCONSIN'S DOOR PENINSULA AND ITS GEOMORPHOLOGY Howard De II er AGS Collection, UW-Mllwaukee and Paul Stoelting University of Wisconsin-La Crosse The Door Peninsula of Wisconsin is one of the premier tourist regions of the American r~iddle West. According to a recent geography of Wisconsin (Vogeler et al 1986,8) , the region is best known for its picturesque sea scape, New England-style architecture, fish boils, and cherry orchards. Among geomorphologists, however, the region is known for the great variety of land form types and for the complex and changing geomorphological processes which have operated in the peninsula. Towering bluffs, sand dunes, lake terraces, abandoned beach ridges, swampy lowlands, and drumlin fields are only some of the many types of landforms to be found in the peninsula. Indeed, the region can be viewed as a unique geomorphological laboratory and an excellent example for classroom study. In this short paper an attempt is made to describe and analyze some of the more prominent landform features of the peninsula and the processes which have influenced their formation. LOCATION AND GENERAL CHARACTERISTICS The Door Peninsula, located In northeastern Wisconsin. is part of the Eastern Ridges and Lowlands province of the state. The peninsula extends in a northeasterly direction into Lake Michigan to separate Green Bay on the west from the main body of Lake Michigan on the east. The peninsula is approximately 64 miles long and about 26 miles wide on its southern end, between the mouth of the Fox River and the city of Kewaunee on Lake Michigan (Map I). -
