The Metcalfe Geoheritage Park, an assemblege of local rock, is our first step towards establishing a network of geoheritage parks across the nation. Thirty blocks of local rock, which are representative of the types of bedrock found in the region, have been assembled in Metcalfe Park beside the Mississippi River in Almonte - immediately south of the recently renovated power plant at the west end of Mill St. Rock types include sandstone, limestone, dolostone, marble, gneiss and diabase and pegmatite. Examples of fossils, cross-bedding, cavity fills, bedding and lamination, intrusion, foliation, lineation, glacial modification, and weathering can be seen.
