The scene above shows the retreat of the Vatnajökull glacier currently underway in Iceland. Views like this would have been common in Central Indiana ~10,000 years ago as the Laurentide Ice Sheet retreated north. As the southern glacial edge moved north, a relatively flat "till plain" surface was left behind that characterizes the northern 2/3 of Indiana today.

The pages below coordinate and tell the story of volunteer projects in and around the till plain region of Central Indiana and the Ohio Valley.
