Michigan
The Geology of Michigan
This live action video is an overview of all the forces which have influenced Michigan for millions of years. It points out the long time periods of time when seas covered Michigan to form thick limestone deposits; it looks at the work of rivers and streams moving material which has been eroded; it studies the evidence of glaciers as they moved over the land, scouring and depositing. It looks at the rocks and minerals of Michigan and the economic importance of these earth materials. This program will give the earth science student an opportunity to see how this land was formed as well as the geologic processes which continue to take place as they slowly change the surface of Michigan.

How The Glaciers Changed Michigan
Glaciers moving over Michigan have probably had more influence on the present appearance of Michigan than any other force. Continental glaciers thousands of feet thick scoured the northern section of Michigan like a giant bulldozer. As they melted they deposited mud, silt, and sand which became the fertile soil of Michigan's rich farmland. The video investigates how the ice came to Michigan; where the various glaciers reached as well as some of the physical features left behind when the ice melted. An excellent introduction to the study of Glaciology.

The Fossils of Michigan
This live active video looks at the ancient life which once lived in the oceans that covered Michigan. Fossil remains of plants and animals have been found in Michigan rocks dating back a half billion years. Many plants and animals have become extinct, but some have managed to survive even to this day. This program will investigate how fossils are formed, the major types of fossils found in the sedimentary rock; what the lands and seas looked like when this entire area was a shallow sea or a swampy marsh.

The Rocks & Minerals of Michigan
While the Native bedrock of Michigan is primarily sedimentary, mainly limestone, sandstone and dolomite, many other igneous and metamorphic rocks can be found all over Michigan because glaciers brought them down from Canada. Precambrian and Cambrian rocks abound in the Northern Peninsula. The copper district of the Keweenaw Peninsula is world famous. This live action video looks at the principle rock types found across Michigan and where they might be found. It also examines the classification origin, and economic importance of these rocks. Our Great Lakes shorelines are treasure laden with a host of truly fascinating gem materials. This presentation is an excellent introduction to the study of mineralogy and can be used as supplementary material for earth science labs.

The Geology of Pictured Rocks National Lakeshore
The geological history of the National Lakeshore is limited to three relatively brief intervals of geologic time: The Cambrian and early Ordovician periods when sediments deposited in shallow seas 500 million years ago became the sandstones that form the Pictured Rocks escarpment; and the Pleistocene epoch when glaciers reworked and mantled the underlying bedrock with a nearly continuous veneer or drift. Bedrock is best exposed along the escarpment where bluffs rise 50 to 200 feet above Lake Superior and extend 15 miles from Munising to the Beaver Basin. Lakes, ponds, bogs, streams, and waterfalls are common throughout the area. Each is performing its task, slowly helping to shape the land and bring its particular attractiveness to the landscape.

The Geology of the Great Lakes
The DVD explores the various geologic and physiographic areas in and around the Great Lake region. Particular attention is given to the role of the glaciers in the formation of the lakes. Photographed on location all over the Great Lakes area, the video includes spectacular footage of Lake Erie, Lake Huron, Lake Michigan, Lake Superior, and Lake Ontario.
