Heading east from Prince George, BC, we climbed steadily into the Northern Rocky Mountains. Before long we were cycling through some of the most majestic and stunning mountains we had ever seen. Power outages, campground closures, and a toothache had us constantly changing our plans. But each day we were rewarded with a sense of wonder at the vast wilderness of rock, ice and forests at the top of the world along the Icefields Parkway in Jasper and Banff National Parks.
