Several students showed up on December 5th, 2009 at the Morton Arboretum to collect our GLOBE weekly atmospheric data.  After examining the temperature data for the week, we went to Lake Marmo  to check for freeze up. Lake Marmo had a thin sheet of ice that was covering 40% of the lake, one week later it was covered from shore to shore.

Lake Marmo is located a short distance from our Weather Station in the Morton Arboretum.  We took 3 pictures of the lake from the site located at the red arrow and then we took 3 pictures of the lake from the site located at the yellow arrow. You can click on the pictures below to see the full resolution.

Even though the lake has a layer of ice, water is flowing under it.

I spotted a Herron down stream.	He looked gold, but he was fishing
