No Flat City


Month: March, 2016
Organization: Toronto and Region Conservation Authority

Many people today think of the GTA as flat terrain. This “No Flat City” map attempts to show that this is not the case due to events such as the Wisconsin glaciation and Isostatic rebound that occurred nearly 12,500 years ago.

For this map, a vertical exaggeration was used to emphasize subtle changes in the topography. As a result, this exaggeration shows the Oak Ridges Moraine boundary, the Iroquois Shoreline boundary and other features such as bluffs, ponds, lakes and rivers created from the past and what we know of our present day landscape.
