Rock Glen Conservation Area is located across the road from Rock Glen RV park near Arkona, ON. our RV stay for a couple of days. I was very fortunate to locate a couple of small fossils (Brachiopods) in the park. These are specimens from the Devonian Era. This little adventure would have been even more fun with our grandkids!! Lots of rugged areas and stairways to challenge me and our lil Yorkie "Ceaser".
