Station 1 THE CLIFF
10
The Cliff is really high
even to Mr. Kowalik!
11
The cliff is erodingdue to the effects of
GRAVITY Which is helped out by the motions of
wind and water
12
Where was this tree a few years ago?
13
If this sign could read itself
14
Once here
Now here!
It would have known to
stay away from the edge of the cliff!
15
You will even be able to HEAR the constant
falling of little gravel avalanches that cascade
downhill!
Avalanche path
16
Erosion sculptures the cliffs into cone and
funnel shapes
17
Storms are removing sand from the beach
Notice the difference in color between the sand
directly in front of the scar and the sand
farther from the scar.
18
What direction is the sand and sediment in the
cliff moving?
19
The cliff is falling! Run boys, run!
20
At the cliff we use clinometers (specially
designed by Mr. Smith) to measure the height of
various beds in the cliff

We will use binoculars to help us determine the
composition of each bed
25
Bed 1, Till Mixture of materials, deposited
directly by the glacier
Bed 2 Mostly sand, with a fair amount of
pebbles
Bed 3 Yellow / Orange color, much more gravel
here
Bed 4 Mostly not visible, covered by fallen
material from above Mixture of sediment
Scar on fan, caused by a storm
26
Lets take a closer look at Bed 1

Notice how warmly dressed these prepared students
are!
Except me! No smile hereIm COLD!

Station 3 Scientists know that glaciers
carried sediment to Caumsett State Park. Using
index rocks students will infer the direction the
glacier advanced

Boulders
41
What minerals will you find in here?
42
Or here?
43
Or here!
