Editor’s note: We want you to Be a Trailblazer this year, so we will be hiking at various preserves throughout the year and documenting it for you. Journey along with us as we blaze a trail through the preserves and hopefully encourage you to do the same.

Taking a trip down south can be a big change in scenery, even if your trip only takes you as far as southern Will County.
If you haven’t been to the sands region of Will County, you might be surprised to see just how distinct it is from other areas of the county. The differences can be subtle at first, but the more you look the more you’ll notice that the prairies and savannas here are unique compared to elsewhere in the county, and that includes the geology as well as the flora and fauna.
The soil here is sandy, and the sandy habitat in this area is the result of catastrophic flooding thousands of years ago, during the Wisconsin Glaciation. When moraines — rock and soil left behind by a moving glacier — were breached by flooding, water poured into the Kankakee River valley, depositing sand across the area.
