Cambridge Ontario Natural Heritage Sites

The city of Cambridge hosts a rich diversity of natural heritage features due to its location at the intersection of several major environmental systems. This Natural Heritage Map is designed to give you an introduction to and description of those systems and features so that you can explore, learn about, enjoy and care for the environment in which we all live. The geology of Cambridge, like that of Southern Ontario, is composed of layers of rock and soil material deposited layer upon layer. The older layers are deeper underground and the most recent layers are at the surface. The rocks are what was left behind by major earth-forming events. These events are often separated by long periods with little change. The rock record is not a continuous documentation of all the events that happened. Often, there are large gaps between events seen in the history of the area’s rocks.
