Rocks tell a story

As someone who enjoys collecting rocks when out in nature, this article struck home with me. In fact, as I told my co-workers just today, my son once did a science fair project on the rocks of Minnesota. The reason they were from Minnesota is because that’s where our family cabin is, where we to each summer for vacation.

The article is entitled “Earthworms’ Castings: Rock Pile” by Jean Ponzi over at the The Healthy Planet. We still have those rocks scattered about the house. After all, they’re really part of the family.
