EarthViewer is an interactive tool that allows you to explore the science of Earth's deep history.
Interestingly Calgary is one of the cities used as a frame of reference. If you check out the ice age you can see the narrow open area running down from the north to the open area of the rest of NA where the Calgary area running along the Rocky Mountains is ice free.

Very cool, thanks for the link.
It shows the Artic had warmed 4°C and Calgary 2°C in the last 40 years. If true that rate is insane, the Artic will have warm beaches in a couple of hundred years and Calgary will be the new Phoenix.
