David Forsyth led a group of 18 hearty Macnamarans, on a frosty Sunday morning, for a tour of the rock formations in Arnprior’s Bell Park and along highway 417, where the newly-exposed rock cut revealed an amazing geological story.  For many of us this is a new area of interest and we left with plans to learn more of our local geology.  Many thanks to Dave and also to Gord Vogg for his assistance.
