Earth Day at Thorn Creek Woods is Saturday, April 22, from noon to 4 p.m. This year we celebrate the soil right beneath your feet. Free fun for all ages!

Did you know that soils are named and classified just like species of plants and animals? Illinois alone has over 700 different types of soil. Come learn how soils are formed and their important role in nature.

There will be lots of fun for everyone; including refreshments, a presentation, several activities, a hike, our Spring Raffle and the opportunity to prepare an edible Mud Pie that you build yourself.

Plant milkweed seeds to take home to grow your own butterfly attracting milkweed plants. Monarch caterpillars feed exclusively on the leaves of milkweed, the only host plant for this iconic butterfly species. Milkweed is critical for the survival of monarchs. Without it, they cannot complete their life cycle and their populations decline. The good news is that planting milkweed in your garden is one of the easiest ways that each of us can make a difference for monarchs.

Investigate the soil builders in a rotting log; creatures that are soil decomposers. Create a soil critter mobile, get a free Pin Oak seedling to take home and take home free soil posters. What is soil made of? Come see & smell and touch the parts of soil at our Soil Table.

The program is free and open to all ages. Registration is not required.

At noon, join us for activities.

At 1 p.m. April Richards will show us what makes up soil and how soil is formed.

At 2 p.m. hike the trails with April to understand the story told by the soil right here in Thorn Creek Woods Nature Preserve.

Become a soil scientist and examine actual soil samples to understand the story told by the layers of soil.

This event is sponsored by Friends of Thorn Creek Woods and the Jim Marzuki Fund for Public Programming.
