High Alkaline Wetlands

 |
If you know about chemistry, you may
know that the opposite of acid is alkaline. Even though lakes and marshes
are normally acid, there are some in Moraine that have a ph level of 8.0,
which means that they are alkaline. It’s a very unique lake and marsh,
and it’s in Moraine.
Most of the marshes evolved after the Ice
Age, some of them were made by
road building. Even though marshes are normally acid, alkaline is
one of the properties of Moraine. There are even different animals due
to the alkalinity.
The study of the alkalinity first started
around 1939 by geologist J. Harlan Bretz. He was from Flossmoor, but he
studied here in the Palos Area. I wonder how much help he had? If he found
out himself, I am personally very impressed. He must have really enjoyed
the subject.
I didn’t know any of this before my interview
with Professor Finley, a professor at Moraine Valley Community College.
He told me all of my information. He was so nice; he even told me more
than I asked. Like, I didn’t ask what a Fen was, but he told me that it
was the late stage of a marsh with no open water. I just used that information
without noticing it!
That is why it is so very unique that the
marshes in Moraine have an unusually high alkaline level. I learned very
much about the marshes and those who studied, or study, them. This alone
would be enough to make the Palos Area special, but it’s just one of many
things.
