Cabot Head lies on a low foreland that extends out in front of the escarpment and that encompasses several wetlands and lakes, including Wingfield Basin, which may have begun as a small lake but is now a lagoon with a shallow entrance to Lake Huron (Georgian Bay).
The gravel road from Dyer Bay out the lighthouse follows a great cobble beach, but what was most amazing was the incredible series of shingle beach ridges on the east side of the point. Shingle - since the rocks are all 6-inch flagstones, all weathered by the several thousand years that has passed since they were last tossed by waves. The fact that they aren't very rounded may indicate that they weren't in the swash zone for very long - a sign of rapidly falling lake levels at the time?
