Chapter 3: Changing Climates
 Glacial erratic, Big Rock. Wikipedia |
In this chapter, you will continue your journey by starting from the beginning of the Cenozoic Era. On your trip you will discover the geological processes that led to the formation of the Cypress Hills, brought Big Rock to Okotoks, and gave the Rocky Mountains a more rugged, craggy face. Grasslands and mammals appear in the changing environment. The journey through the Cenozoic Era will not just involve travel in Alberta but with Alberta. |

During this era, Alberta itself migrated north to its present position! With the migration, Alberta went through a dramatic climate change—from a tropical to a temperate climate. You will also see climate change as a global phenomenon that continues to the present. Projections show that climate change may now be affected by a new factor—the emergence of human civilizations.
