Work with the gravel, sand, or rocks available near your home.

 Rock Snails

Yes, the Egg Salad Snail joined in! 
[Type Egg Salad into the Search Tool to revisit that April snail.]

If they could speak of the events that shaped their existence, what would we learn?
Minnesota has a rich geological history!

So now I'm thinking about a few rocks I brought home from a summer camping vacation in Whitewater State Park. We learned, from the park information,of a nearby opportunity to look for old rocks having been exposed with the cutting away of a hill to build a highway.

 400 million years ago southeast Minnesota was a shallow sea.
 This is fossil evidence.

Wait! Is that a snail?
