Jasper National Park is truly amazing – beautiful rivers and valleys, several peaks over 3,000 meters, and an overall stunning geology. The western ridge forms the continental divide, separating streams that flow east and north to the Arctic Ocean or Hudson Bay from those which drain westward to the Pacific Ocean. Here, we see a tilted mountain composed of folded limestones. I’m sorry I can’t tell you more about what’s happening here tectonically, and even the author of the picture, reddit user PetroGeol.
