A Note From the Road: Holes - Hagarville, Arkansas

Dear Henry,

While hiking near Pam's Grotto all of the limestone cliffs had these holes in it.

At first, we thought the holes were caused by water drops or something like that.

Nope, they are caused by mollusks, who created holes to burrow in.  

This area used to be (many eons ago) under water. 

It was an interesting walk through geology.

xoxo a.d.
