Transcript Five Regions of Wisconsin

*
Take notes on the following major points of
Wisconsin’s geography and five regions.
* On the Great Lakes (Superior and Michigan) and
the Mississippi River on the west.
* Population capacity depends upon:
* Topography
* Soil and climate
* how can we survive/use a given area?
*
*Soil as a Resource
* Two centuries and a half ago, fur-bearing animals
were our greatest asset (location of trade)
* Forty years ago, pine forest was our greatest
asset (lumber industry)
* Farm produce – wheat (hay, oats, and corn),
dairying
* Manufacturing
*
* Related to the use of the land by plants, by
animals, and by man
* Each differs in:
* roughness or smoothness of topography
* infertility or sterility of soil
* climate
* adaptation by wild/cultivated plants, animals,
and by man.
* Driftless vs. Glaciated Regions
*
* Most attractive part of the state – “mountainous”
* Driftless Area
* Baraboo Range – Devils Lake State Park
* Was completely surrounded by glaciated territory and is a
*
*
*
large sample of what the rest of WI, as well as northern and
eastern U.S. were like before the Glaciation period.
Highland to the north furnished temporary protection from
the ice invasion
Rapid movement of glacial lobes in the lowland and west
resulted in the final joining of these ice lobes south of the
area, so that it was completely surrounded
Termination of forward movement (temperatures raised)
began the retreat before the area was covered (followed their
original path)
* Mississippi River – 1673 Pere Marquette and Sieur Joliet
*
* Largest proportion of the population – due to level
topography, fertile soil, and favorable climate.
* Drumlins made by continental glaciers (these and
the Driftless Area are what make WI known)
* Tell us what direction the glacier moved
* 5-140 feet above the adjacent plain, and range from
narrow to 2 miles wide
* Kettles – deep hollows (some were filled with water
and are now lakes or ponds)
* Eskers – built by glacial streams flowing beneath
the ice – narrow winding ridges of gravel (some are
as long as 6 miles)
*
* Not a continuous plain
* Division of northern and southern WI (transition
zone)
* Region of low hills
*
* Prior to the glaciation, Wisconsin was part of a
mountainous region similar to that of the Alps –
worn down mountains have been revealed
particularly in this area.
* Rapids and waterfalls are abundant in the streams
and lakes and swamps are found everywhere
* Better suited for forest than to crops with large
swampy areas (huge for the lumber industry) –
steady water supply
* Attraction to fishermen and visitors.
* Rapids and Waterfalls furnish invaluable water
power.
*
* Lake Superior is the largest body of fresh water
in the world
* Was a highland and is now a lowland because of
the dropping of a block of the earth’s crust in a
fault
* Chiefly a plain
