The Pinnacle is a large morainic hill on the north side of Shaw’s Creek providing a spectacular view of the rolling Caledon hills. It rises steeply north of Shaw’s Creek behind the Upper and Lower mill sites and looms over the Alton settlement area.
The hill was completely denuded of trees by 1890. The combination of the Pinnacle and Shaw’s Creek defined the shape of the village as it grew and both remain key local focal points.
