How old is the Prosser Layer in the cave?

• A. 400 million years ago
• B. 451-452 million years ago
• C. 440 million years ago
• D. 460 million years ago

Answer: (B)

The Prosser Layer in Niagara Cave dates back to approximately 451-452 million years ago, placing it in the Middle Ordovician period of the Paleozoic Era. This timeframe is significant as it represents a time of considerable geological change and the evolution of marine life. The specific age range is based on geological studies and stratigraphic correlations that have allowed scientists to date the rock layers precisely. This level of geological understanding is crucial for tour guides, as it helps them convey the history of the cave’s formation to visitors, emphasizing the length of time involved in shaping such a natural wonder and the biological and environmental conditions that existed during that period. Understanding these layers not only enriches the narrative of the cave's history but also enhances the overall educational experience of the tour.
