Geology
The main feature of the area is the Spencer Gorge, a Y-shaped gorge around in length, with the depth reaching. The walls of the gorge are very steep, contrasting the gently sloping landscape found in the nearby areas. The gorge was incised by the melt streams of the Wisconsin glaciation about 10,000 years ago. The gorge displays a near-complete stratigraphic section from the red shales of the Queenston Formation to the caprock of the Lockport Formation.Waterfalls
Measuring in height, Tew's Falls is the tallest waterfall found in Hamilton, among 96 others.Located at above the sea level, it is also the highest waterfall in the city. Webster's Falls is another major waterfall. With its crest, it is the largest within the city.
The gorge is an excellent example of the process of waterfall recession. At least 10 bowl-shaped basins have been identified within the area, indicating the earlier positions of the waterfall. Some of the largest and the oldest identified basins have the diameter of up to, with depth of up to, making them comparable to the present state of the Horseshoe Falls.
