#2 After a Fire

Hopewell Hill Prairies Nature Preserve, Illinois

This hill prairie lies on a terminal moraine from the Wisconsin Glaciation. Rocks were carried along in the ice from further north and then left behind when the glacier melted, some 10,000 years ago, more or less. After a fire, pebbles and larger stones can be seen embeded in the soil.
