                         Built 100 Miles of Kettles
   A     T THE junction of the ice tongue which pushed down Lake Michigan;
with the one which moved down Green Bay, there was deposited along the higher
land between them one of the most impressive glacier-built ranges of hills
on the continent - the great Kettle Moraine. This extends from close to the
southern boundary of the state, near Lake Geneva, for a hundred miles north-
ward. It is a broad belt of most irregularly deposited material - humps and
hollows (the latter called kettles and giving the name to the moraine),
boalder strewn slopes and serpentine ridges, small lakes and marshes, and
and there a stream twisting back and forth in an apparently hopeless attempt
to find its way out of the maze.
     No road can follow a straight course in this Kettle Moraine, and no
traveller can predict the prospect that will be disclosed by the turn in
road a hundred yards ahead. It may turn abruptly about a "kettle"
full of
water - a lakelet too small to make even a dot on the map - or it may dis-
close a hillside pasture with a herd of Guernsoys or Holsteins. A few hun-
dred yards farther it may enter a sunny open. wooded area, and wind through
on ever changing levels for a mile or two.
     Kettle Moraine is not a range of hills that stand up in marked eleva-
tion above the surrounding area. The elevations are all moderate. Hills
with a vertical distance much more than a hundred feet from base to summit
are uncommon. Much of the material used by the glaciers to build up these
hill_ is gravel. Again the comparison of the ice sheet to a great millstone
comes home to us. In the grinding process the softer materials of the rocks
were ground finest and only the harder and better stone was left as pebbles
and bowlders. Thus this prehistoric millstone was working for the Wisconsin
of today and piling up groat stores of gravel of selected quality - ready
prepared building material, which is now used in groat quantities in building
roads and concrete structures.
                           Work of a Master Sculptor
      IT WAS a masterly task that the glacier accomplished. It is difficult
to picture to oneself when driving over this broad gently-rolling area dotted
with farm homes and villages, that here once was a preglacial valley, now
buried to a depth of five or six hundred fect, or that a mile away the old
rock wall in the valley comes to within fifty foot of the present surface.
The glacier did not always complete its work. Some of the old valleys it
partly filled, depositing a little material at one spot and piling it high
     Some master of design must have guided this erratic workmanshipm since
it resulted in the most attractive features of the landscape - the thousands
of lakes that dot the whole glaciated portion of the state. The low places
in the old valleys filled with water and the higher glacial deposits were
the dams which held it back.
