Geocache Description:


you will be driving over hilly till, stopping to get a picture
to post and then answer at least one question from below. i think
all the info needed is on the page, but if you would like i have posted
a link to the online free wiki on moraine. beware this link is user
edited so i can't say for sure it will always be completely right.
http://en.wikipedia.org/wiki/Moraine

As anyone who owns a sled in the Hancock, Wood, and/or Lucas
counties can tell you Northwest is rather flat. That's due mostly
to the repeated scraping of a continental glacier that formed in what
we now call Canada. The Canadian snows packed down on top of
yet more snow and ice, forcing the glacier to move/push/scrape south.

As it pushed south the glacier acts as a large sander flatting out the earth
in that area. Then as it melts North it drops all sorts of debris
from along its path. This mixture of soils, rocks, and sometimes (but
not too much around here) mammoths, is called till. If the right
conditions exist (those being equal new formed ice pushing south, and equal
heat melting north) it appears to a neutral observer that the glacier isn't
moving north or south; it looks like it is staying it the same spot, dropping
large piles of till.

The large long piles of till that form at the end of the "stationary" glacier
are called terminal moraines. There just so happens to be one that runs
right through the north side of Findlay and the south side of Van Buren.
It has been named the Defiance Terminal Moraine after the city of
Defiance, OH.

If you follow your GPS and points I listed here you will drive from the
top of it to the bottom. However it is very hard to head north of Findlay
and miss it.



Directions are given from south to north
Go to Point A N41 04.867 W083 37.295 
        at the intersection of CR 99 and TR 230 turn north
At point B(int TR 230 and CR 108) N41 06.551 W083 37.299
        turn left on to 108
At point C(int TR 229 and CR 108) N41 06.990 W083 37.296
        turn back to the north
AT point D(state park resting fishing eating area) N41 08.055 W083 37.864
         get out and take a picture here than keep going north.
At point E the moraine is at its northern most edge. N41 09.169 W083 37.883



Your GPS might have a way of measuring your elevation, so you should
be able to find yourself on the cross section fairly easily.

Now it's time for some geology questions. Answers should be emailed to
me - do not list the answers in the post even encrypted. Thanks a
million. A detailed cross section can be found Here.
Question 1
How do we know the glacier did not go south after it started moving
again?(we know it moved because there isn't a mile high wall of ice
north of Findlay)

Question 2
At which point listed above ABCDE did the glacier stay at the longest
in this end moraine?(assume that rate of debris being piled up doesnt change, only the movement of ice.)

Question 3
EXTRA CREDIT(you don't get anything extra for it but the feeling
of satisfaction) There are several valleys in the formation. Do you think
the glacier left those valleys behind or do you think the river and creeks
made them all on their own?

Additional Hints (No hints available.)
