Tiplin Creator  Astrid Akkerman from a sketch by A.H. Tiplin Type  Still Image Collection  Niagara Falls Public Library Digital Collections Notes  On January 19, 1887, the Niagara Falls Gazette reported; " Wednesday night last a large section of rock on the Canadian side, close to the Horseshoe Fall, fell with a deafening crash and jarring the earth for some distance away. The exact position of the break, which was 150 feet (46 metres) long and 60 feet (18 metres) wide, was the point visitors will recall. It was close to the Horseshoe falls and protected by an iron railing. So little remains of the once famous Table Rock that it can hardly retain its name. It originally extended out so far that a person on the edge stood directly in front of a portion of the Horseshoe Falls. In 1818 a mass 160 feet (49 metres) by 30 or 40 feet (9 to 12 metres) in width fell. In the winter of 1828 and 1829 several large masses fell leaving the table-shaped ledge without support on the North and South sides. About mid-day on June 26th, 1850, this table fell with a terrible crash which startled inhabitants in the vicinity, the first impression being that an earthquake had occurred. It is said that a solitary stableman who was washing an omnibus on the rock escaped with his life, the vehicle, of which no traces were ever found, falling into the abyss. In 1862, several pieces of rock were blasted off as a prevention of accident." In 1897 other pieces broke off, leaving Table Rock as only a slight projection. Finally in 1935 what was left of the overhang was blasted off as a safety precaution. Table Rock remains today in name only.

Title  Former Outlets of the Great lakes from "Our Romantic Niagara" by A.H. Tiplin Creator  Astrid Akkerman from a sketch by A.H. Tiplin Type  Still Image Collection  Niagara Falls Public Library Digital Collections Notes  This sketch shows the former outlets of the Great lakes before the Falls cut back to the Glen. The arrow represents the slow retreat of the melting glacier, over a period of thousands of years. When the glacier was north of District "A" on the map, the easiest course for the melt waters was the Nipissing-Ottawa Outlet. When the surface of the land along this outlet rose after the weight of the glacier was removed from it, a new and lower passage for lake drainage opened up at "B", through Lake Simcoe and the Trent Valley System on to Lake Iroquois. The dotted area marked "E" shows the approximate size of the small Lake Erie whose waters formed stage II, the Old narrow or Erie Gorge. Modern lake Erie is shown at "C".
