Guffin Bay is separated from Chaumont Bay by Point Salubrious and which island?

The correct answer is Cherry Island. Cherry Island is located in the area between Guffin Bay and Chaumont Bay in Lake Ontario, providing a natural separation between the two bodies of water. This geographical positioning is significant as it influences local navigation and fishing patterns. Understanding the location of Cherry Island helps in comprehending the layout of the bays and their associated ecosystems.

Additionally, other islands like Bass, Stoney, and Howe do not serve the same role in separating Guffin Bay from Chaumont Bay, as they are situated in different areas or do not provide a significant barrier between these two specific bays. Knowing the correct island enhances one’s local knowledge, which is crucial for safe navigation and awareness of the area's natural features.
