How old is Niagara Cave estimated to be?

The correct estimate for the age of Niagara Cave is approximately 450 million years, which places it in the timeframe when significant geological formations were occurring in the region. This estimation is supported by the understanding of the geological history of the area, which indicates that the limestone layers in which Niagara Cave is carved were formed during the mid-Ordovician period. This period is characterized by a warm, shallow sea environment conducive to the deposition of sediments that would later solidify into limestone.

The age reflects the time it would take for the geological processes involved in the formation of such caves, including erosion and mineral deposition. Recognizing this timeframe is crucial for understanding not just the cave’s formation but also the broader geological history and the ecosystem that developed around it over millions of years.

Other estimates provided do not align with the geological evidence and studies that indicate a closer association with the mid-Ordovician period, demonstrating the importance of having accurate information about the natural history of such significant geological features.
