The Rocky Mountains stretch 3, km (1, mi) in straight-line distance from the northernmost part of British Columbia, in western Canada, to Countries: Canada and United States.

Triassic rocks are widely distributed through the Rocky Mountain Region from Idaho and Wyoming to Arizona and New Mexico, constituting one of the greatest areas of continental Triassic deposits in North America.

Here continental red beds predominate, though marine members of older Triassic. For million years, the focus of the effects of plate collisions were near the edge of the North American plate boundary, far to the west of the Rocky Mountain region.

It was not until 80 Ma these effects began reaching the Rockies. The current Rocky Mountains arose in the Laramide orogeny from between 80 and 55 multdemsvote.comnates: 39°07′04″N °26′43″W / °N.
