MVFN members arrived at Metcalfe Geoheritage Park in Almonte by car, on foot, and on their bicycles.

WHAT ?   This was a full day geoheritage tour to examine and reflect on the geoheritage of our area.

 In this postcard image (an artist’s interpretation of our local environment during the lower Ordovician period) one can see that about 470 million years ago a tropical ocean teeming with marine life covered our region.

The local metamorphic, sedimentary, and igneous rocks on display at Metcalfe Geoheritage Park in Almonte tell a story of towering mountains, ocean depths, colliding continents, and a landscape locked in ice over the past 1.2 billion years.

The group continued the tour after lunch, traveling via car-pool to two additional sites of interest.
