Title

Future of the Falls from "Our Romantic Niagara" by A.H. Tiplin

Description

en-CA In the 30.6 kilometres (19 miles) between the Lockport Limestone at Goat island and the Onandaga Limestone at Buffalo, the types of bedrock will cause the cataract to change a great deal. In the sketch, S= Silurian Age sea-beds composed of: I, Salina Limestone; II, Lockport Limestone; III, Clinton and Median shale and limestone formations; D, Devonian Age limestones which form the escarpment through Buffalo and which prevent Lake Erie from draining almost completely into the Niagara River; G, end of Goat island. The Falls will be much higher after cutting through the terraces of the ancient buried Falls-Chippawa valley; R, near here, at the southern end of Navy island, the Falls with either become a terraced cataract, like Letchworth Lower Falls, or will become a rapids because of the soft Salina shales which form most of the bed of the Upper Niagara River; P, Peace Bridge, where there now are rapids of a sort and the future site of another small cataract when the level of the Niagara River is gradually lowered by the falls cutting through the shales at "R".
